True or false, 4x-3+x+7 would equal 5x-10
Answer:
false
Step-by-step explanation:
if you simplify you get 5x+4=5x-10, which is false
Answer:
False
Step-by-step explanation:
Step 1:
4x - 3 + x + 7 = 5x - 10
Step 2:
5x - 3 + 7 = 5x - 10
Answer:
5x + 4 ≠ 5x - 10

Solve the equation. Show your work / explain your steps. x - 5 + 3x = -21
Answer:
X = -4
Step-by-step explanation:
See image for explanation
Answer:
x=4
Step-by-step explanation:
x - 5 + 3x = -21
add 3x and x and add 5 to both sides of the equation
4x = -16
then divide both sides by 4
x = 4
ya answer is x = 4
Solve for x -4x + 3x = 2
Answer:
No Solution
Step-by-step explanation:
x-4x+3x=2
0x=2
0=2 or x=2/0
Either way, no solution
Daniela sells handmade purses for $22. She
makes $15 after expenses for each purse she
sells. She has $71 in the bank. How many
purses will she need to sell in order to have a
total of $161 in the bank?
Answer:
6 purses
Step-by-step explanation
1. Subtract 71 from 161 as that's how much Daniela needs to make to have 161, which is 90
2. Divide 15 by 90 as 15 is the profit, so the answer would be the amount of purses she needs to sell, then you get 6
Check
6 times 15, 90
71 + 90 = 161

Priya starts with $50 in her bank account. She then deposits $20 each week for 12 weeks.
How many weeks does it take her to have $250 in her bank account?
O 15 weeks
O 4.6 weeks
O 10 weeks
O 5.4 weeks
Answer:
10 weeks
Step-by-step explanation:
20x+50=250
First subtract 50 from both sides, which gives you 20x=200
then divide 20 from both sides which gives you x=10
Your friend, Jamie, rolled a number cube and got the number 5. On his next turn, he says he won’t be able to roll another 5 because he is only expected to roll a 5 once every six rolls. Is your friend correct? Explain your answer.
Answer:
No
Step-by-step explanation:
Even though he has a 1/6 chance of rolling it he still has a 16.67% percent chance
Answer:
here's the sample answer!
Jamie is not correct. No matter how many times the cube is rolled, the probability of rolling a 5 will be 1/6.
Step-by-step explanation:
E varies directly with G. When G is 6, E is 10. Find the value of G when E is 18.
Answer:
10.8
Step-by-step explanation:
E has increased by a factor of 18/10 = 1.8, so G will increase by that factor. The corresponding value of G is ...
6 × 1.8 = 10.8 = G
__
If you like, you can write an equation relating G to E:
E = kG
10 = k(6)
k = 10/6 = 5/3
Now for E = 18, we have ...
18 = (5/3)G
18(3/5) = G = 10.8
18- 12y = -22 -7y solve for y
Answer: y=8
Step-by-step explanation:
To solve for y, you want to use algebraic properties to isolate y.
18-12y = -22-7y [add both sides by 7y]
18-5y=-22 [subtract both sides by 18]
-5y=-40 [divide both sides by -5]
y=8
Now, we know that y=8.
what is the answer to 6(2x+3)-6
Answer:
12x+12
Step-by-step explanation:
first you distribute the 6 into the parenthesis.
so it becomes:
12x+18-6
Then you solve the common terms:
12x+12
& thats your answer!
Answer:
12x +12
Step-by-step explanation:
6(2x +3) - 6
12x +18 - 6
12x +12
60 and 108 The GCF IS
Answer:
Greatest common factor (GCF) of 60: 223
Greatest common factor (GCF) of 108: 22333
The Greatest Common Factor (GCF) is: 2 x 2 x 3 = 12
Step-by-step explanation:
To get the Greatest Common Factor (GCF) of 60 and 108 we need to factor each value first and then we choose all the copies of factors and multiply them.

Answer: -5What is the discriminat of 9x²+2=10x
Answer: 28
Step-by-step explanation:
The discriminant in the quadratic equation which is
it is the part inside of the square root part
it is called the discriminant beause it tells you how many real or complex roots/solutions you will get
so b^2-4ac
convert to ax^2+bx+c=0 form
9x^2+2=10x
subtract 10x
9x^2-10x+2=0
ax^2+bx+c=0
a=9
b=-10
c=2
substitute
-10^2-4(9)(2)
100-36(2)
100-72
28
discriminant is 28
Hi can someone tell me how is the answer 113?? how do i type it in the calculator?? im confused can someone please explain ASAP!!!!!!!!
THANK YOU
You shouldn't need a calculator for this. The quadratic equation is written in standard form.
ax^2 + bx + c = 0
You substitute a, b, and c into the discriminant formula and solve as shown in the example in the picture you provided.
(-7)^2 - 4(2)(-8)
49 - 4(-16)
49 - (-64)
49 + 64
113
Best of Luck!
h(x) = x2 + 1 k(x) = x – 2 (h – k)(3) =
Answer:
3x^2 - 3x - 3
Step-by-step explanation:
Plug in the equations in place of the variables
First, subtract k(x) from h(x)
x^2+1-x-2 (combine like terms)
x^2 - x -1
Next, multiply the new equation by 3
3(x^2 - x - 1) Use distributive property
= 3x^2 - 3x - 3

Solve the quadratic equation by factoring. 2x^2+5x+3=0
Answer:
-0.33 repeating
Step-by-step explanation:
2x^2=4x
4x+5x+3=0
combine like terms
9x + 3 = 0
subtract 3 from both sides
9x = -3
divide 9 both sides to get the variable by itself
x = -0.33 repeating
Answer:
[tex]x_1=-\frac{3}{2} \\\\x_2=-1[/tex]
Step-by-step explanation:
the general fromula is
[tex](ax+b)(cx+)d)\\\\=acx^{2} +(ad+bc)x+bd[/tex]
so we need that
[tex]ac=2\\\\ad+bc=5\\\\bd=3[/tex]
for ac = 2
we only have 2 and 1
so let's say
[tex]a=2\\\\c=1[/tex]
so we now have
[tex](2x+b)(x+d)\\\\2x^{2} +(2d+b)x+bd\\\\[/tex]
and for bd = 3
we only have 3 and 1
but we need to
2d +b = 5
so we can have
b=3
and
d=1
so the factorized form is
[tex](2x+3)(x+1)[/tex]
so we come back to
[tex](2x+3)(x+1)=0[/tex]
so here we have two cases
Case 1
[tex](2x+3)=0\\\\2x+3=0\\\\2x=-3\\\\x=-\frac{3}{2}[/tex]
Case 2
[tex](x+1)=0\\\\x+1=0\\\\x=-1[/tex]
so those are our solutions

In the expression 3v – 8, what is the variable?
Answer:
V is the variable
Step-by-step explanation:
Answer:a. v
Step-by-step explanation:
Given
Required
Identify the variable
Literary, variable means things that change in values;
Going by this definition, we have that:
3 -> This is not a variable because its value will always be 3
v -> This is a variable because its value can change once its value changes, the result of the expression will also change
- -> This is not a variable; it is an arithmetic operator to subtract
8 -> This is not a variable because its value will always be 8
Take for instance
When
Notice that there's a difference in both results;
This is as a result of v being a variable

Miguel did the following math problem: 65 ∙ 64 = 369. Which of the following is a true statement? 1.He is correct. 2.He is incorrect because he should have subtracted the exponents. 3.He is incorrect because he should have multiplied the exponents. 4.He is incorrect because he multiplied the bases.
Answer:
He is incorrect.
Step-by-step explanation:
The correct answer is 4,160.
Answer:
3. He is incorrect because he should have multiplied the exponents.
Step-by-step explanation:
6∧5 × 6∧4 = 369 Incorrect
Correct: 6∧5 = 7776
6∧4 = 1296
7776 × 1296 = 10,077,696
1. He is not correct, therefore the first answer is wrong.
2. You do not subtract the exponents unless one of the exponents is negative and you have the same bases. You have the same bases in this equation, however, neither one of them are negative. Therefore, the second answer is wrong.
3. The third answer is correct because if you were adding the two terms together then you would add the exponents together then multiply the base as many times as needed. However, since you are multiplying the two terms together, you also need to multiply the exponents together. From there, you then multiply the terms and get your answer.
4. The fourth answer is also incorrect because you need to multiply the bases together in order to get a correct answer.
