Simplify 7x^2 + 3 - 5(x^2-4)
Answer:
2x^2 + 23
Step-by-step explanation:
For this problem, we will simply combine like terms after using the distributive property:
7x^2 + 3 - 5(x^2 - 4)
= 7x^2 + 3 - 5x^2 + 20
= 7x^2 - 5x^2 + 3 + 20
= 2x^2 + 23
Cheers.

0.4x - 5 = 0.08x + 3 srry I forgot the x
Answer:
x= 25.
Step-by-step explanation:
To isolate "x", I first moved all terms containing x to the left side of the equation: 0.32x-5=3 (0.4-0.08=0.32). Then moved all terms not containing x to the right side of the equation: 0.32x=8. Finally, I divided 8 by 0.32 which equals 25. Thus, x=25. I hope this helped!
HELP!!!Find the measures of angles 1, 2, and 3. Show your work. Choose the correct measures of each angle. A. m∠1=77° m∠2=103° m∠3=77° B. m∠1=77° m∠2=103° m∠3=76° C .m∠1=75° m∠2=103° m∠3=75°
angle 2 = 103° ( vertically opposite angles )
angle 1 = angle 3
103° + 103° + 2 ( angle 1 ) = 360° ( angle 1 = angle 3 )
or, 206° + 2 (angle 1) = 360°
or, 2(angle 1) = 360 - 206
or, 2(angle 1) = 154°
or, angle 1 = 154/2 = 77°
Answer:angle 2 = 103° (vertically opposite angles)
angle 1 = angle 3 = 77° (vertically opposite angles)

If y= 55 when x = 120 what is the value of y when x = 60 ?
Answer:
equation calculator help u out
Answer:
y = 27.5
Step-by-step explanation:
120 (x) - 55 (y) = 65
65 / 2 = 32.5
60 - 32.5 = 27.5
x = 60 and y = 27.5

what is the sum of the equation? 15x-5x+5y+5y
Hey there!
ANSWER: [tex]10x+10y[/tex]EXPLANATION:[tex]15x-5x+5y+5y[/tex]
To solve, first subtract the 2 numbers with x.
[tex]15x-5x=10x[/tex]
Now let's add the two numbers y.
[tex]5y+5y=10y[/tex]
So the answer will be 10x + 10y because 15x-5x is equal to 10x and 5y + 5y is equal to 10y. And then you just add the x and y.
[tex]10x+10y[/tex]

It cost Hudson $28.20 to send 188 text messages. How much would it cost to send 63 text messages? Good luck!
Answer:
$9.45
Step-by-step explanation:
1. First, you want to figure out how much one text message costs. To do this, divide the dollar amount (28.20) by the number of text messages (188). You get 0.15, or $0.15 per text message.
2. Using this $0.15 per text message, you can calculate how much 63 text messages costs. You simply multiply $0.15 by 63 to get $9.45, which is your answer.
Hope this helps! :)
Sorry I also need help with this question
Answer: B
Step-by-step explanation:
(f/g) means to divide f(x) by g(x).
[tex](f/g)(x)=\frac{3x+2}{3x-5}[/tex]
To find the domain, you set the domain equal to zero and solve for x.
3x-5=0 [add both sides by 5]
3x=5 [divide both sides by 3]
x=5/3
Now, we know that B is the correct answer.
-8(7x+8)=-8x+34 i need help solving this equation .
Answer:
x = -49/24
Step-by-step explanation:
The first step in solving this equation is to use the distributive property to eliminate the parentheses on the left side of the equation.
-8(7x+8) = -8x + 34
-56x - 64 = -8x + 34
Next, we should add 8x to both sides of the equation.
-48x - 64 = 34
Next, we can add 64 to both sides of the equation.
-48x = 98
Finally, we can divide both sides of the equation by -48 to get the variable x alone on the left side of the equation.
x = -98/48 = -49/24
Therefore, the correct answer is -49/24.
Hope this helps!
what is Z 2(2z -4)=4
Answer:
z=3
Step-by-step explanation:
2(2z -4)=4
Divide by 2
2/2(2z -4)=4/2
2z-4 = 2
Add 4 to each side
2z-4+4 = 2+4
2z = 6
Divide by 2
2z/2 = 6/2
z=3

Use f(x)=-3/2x+11, g(x)=x^2-7x, and h(x)=|15-9x| to evaluate the function h(2/3)= ________
Answer:
The answer is nine
Step-by-step explanation:
The required solution of the the function is 9.
It is required to evaluate the function.
What is function?A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.
Given :
Now the given function is,
f(x)= -3/2x+11
g(x)=x^2-7x
h(x)=|15-9x|
To evaluate the function
h(2/3)
Put x = 2/3 in h(x) we get,
h(x) = |15 - 9(2/3)|
h(2/3)= |15 - 18/3|
h(2/3)= |15 - 6|
h(2/3)= |9|
h(2/3)= 9
Therefore, the required solution of the the function is 9.

Step-by-step explanation:
A restaurant manager states the number of customers that enter the
restaurant is equal to 3 times the number of people that buy a hotdog from
the hotdog cart plus 15.
The manager also states that the number of customers that enter their
restaurant is equal to 2 times the number of people that buy a hotdog from
the hotdog cart plus 60.
What number of people buying a hotdog from the hotdog cart across the
street makes the equation 3x +15 = 2x +60 true?
Answer:
Yes, that is true, and x=45.
Step-by-step explanation:
Yes, that's how you set up the equation I also listed the sets to solve it below:
3x+15=2x+60
-2x. -2x
--------------------
x+15=60
-15 -15
------------------
x=45
You can also plug it in to check your work.
3(45)+15=2(45)+60
135+15=90+60
150=150

Rachel's chocolate bar is 43% cocoa. If the weight of the chocolate bar is 68 grams, how many grams of cocoa does it contain? Round your answer to the nearest tenth.
Answer:
29.24 grams
Step-by-step explanation:
It is given that,
Rachel's chocolate bar is 43% cocoa
The weight of the chocolate bar is 68 grams
We need to find how many grams of cocoa does it contain. It means it will contain 43% of 68 grams. It can be solved as follows :
[tex]C=\dfrac{43}{100}\times 68\\\\C=29.24\ \text{grams}[/tex]
Hence, it will have 29.24 grams of cocoa.
