Answer:
3^3+2(3)(7)(-3)-5(-3)^2=-144
hope this is your required answer
Answer:
-144
Step-by-step explanation:
a³ + 2abc - 5c² = (3)³ + 2(3)(7)(-3) - 5(-3)²
= 3³ + (-126) - 5(-3)²
= 27 + (-126) - 45
= (-99) - 45
= -144

Answer:
a. 2x +y = 10; 2x +3y = 22
b. 6 minutes
Step-by-step explanation:
a) The problem statement tells you that ...
x = minutes around the block
y = minutes around the park
2x +y = 10 . . . . twice around the block and once around the park: 10 min
2x +3y = 22 . . . twice around the block and 3 times around the park: 22 min
__
b) Subtracting the first equation from the second gives ...
(2x +3y) -(2x +y) = (22) -(10)
2y = 12 . . . . . . . . simplify
y = 6 . . . . . . . . . divide by 2
It takes you 6 minutes to jog around the park.
Answer:
Part A) The system of equations is
[tex]2x+y=10[/tex]
[tex]2x+3y=22[/tex]
Part B) The number of minutes it takes you to jog around the park is [tex]6[/tex] mins
Explanation:
Part A) Write a system of linear equations
Let [tex]x[/tex] ----> the number of minutes it takes you to jog around the block
Let [tex]y[/tex] ----> the number of minutes it takes you to jog around the park
we know that [tex]2x+y=10[/tex] ----> equation A
and [tex]2x+3y=22[/tex] ----> equation B
Part B) How long does it take you to jog around the park?
Multiply equation A by [tex]-1[/tex] both sides
[tex]-1(2x+y)=-10[/tex] ----> [tex]-2x-y=-10[/tex] ----> equation C
Adds equation B and equation C
[tex]2x+3y=22[/tex]
[tex]-2x-y=-10[/tex]
____________
[tex]3y-y=22-10[/tex]
[tex]2y=12[/tex]
[tex]y=6[/tex] minutes
Find the value of [tex]x[/tex]
[tex]2x+(6)=10[/tex]
[tex]2x=10-6[/tex]
[tex]x=4/2=2[/tex] minutes

In a piggy bank on his dresser, Tom has a total of $2.85 in pennies and quarters. If
the number of pennies is 5 more than three times the number of quarters, how
many pennies and quarters does he have in his piggy bank?
Number of pennies in piggy bank will be 35.
Number of quarters in piggy bank will be 10.
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
Total cost in piggy bank with pennies and quarters = $2.85
And, The number of pennies is 5 more than three times the number of quarters.
Let Number of quarters = x
And, Number of pennies = y
= 5 + 3x
Since, Total cost in piggy bank with pennies and quarters = $2.85
So, we can formulate;
0.25x + 0.01y = $2.85
Substitute the value of y as;
0.25x + 0.01(5 + 3x) = 2.85
0.25x + 0.05 + 0.03x = 2.85
0.28x + 0.05 = 2.85
x = 10
And, y = 5 + 3x = 5 + 3 × 10 = 35
Thus,
Number of pennies in piggy bank will be 35.
Number of quarters in piggy bank will be 10.

Is (1,-4) a solution to the equation y=-2/?
A yes
В. no
Answer: B.no
Step-by-step explanation:
To figure this out, plug (1, -4) into the equation y=-2x. 1 is the x value, so we plug it into the x. -4 is the y value, so we plug it into the y spot. In the end we get -4=-2(1). Is this true? No, it isn't. Therefore it is not an answer
Which statement about the relation is true?
A.The relation is a function of x because each value of x corresponds to only one value of y

Write an equality and then solve it. Sonya is a waitress. She earns $200 a week plus 15% tip in the cost of each meal she serves. What is the least amount of the total cost of the meals she serves in order for her to earn at least $450 each week. Answer this seriously or you’ll be reported
Answer:
$1666.67
Step-by-step explanation:
$450 is the total amount she earned and $200 is the weekly wage she received. That means that $250 came from tips.
$200 + .15 (x) = 450
.15x=250
x=$1666.67

(b) it takes 44 pounds of seed to completely plant an 8
-acre field.
How many pounds of seed are needed per acre?
pounds per acre
Check
Answer:
5 pounds and 8 ounces of seed per one acre.
Step-by-step explanation:
We have our two values, 44 pounds and 8 acres.
It also says it takes 44 pounds of seed for every 8 acres of farmland.
So to get the value of how much seed per one acre we need, we divide 44 by 8.
Doing so yields us 5.5 pounds, which can be converted to 5 pounds and 8 ounces. (remember 16 ounces is 1 pound)
1) 0.0 + 5.5 = 5.5
2) 5.5 + 5.5 = 11.0
3) 11.0 + 5.5 = 16.5
4) 16.5 + 5.5 = 22.0
5) 22.0 + 5.5 = 27.5
6) 27.5 + 5.5 = 33.0
7) 33.0 + 5.5 = 38.5
8) 38.5 + 5.5 = 44.0
Divide: 83.5 ÷ 6.25 The first step in solving 83.5 ÷ 6.25 is to multiply the divisor and dividend by . The new division problem is .

What two rational expressions sum to 3x-4/x^2+x-12 ? enter your answer so that each rational expression is in simplified form
The rational expression [tex]\frac{3x - 4}{x^2 + x - 12}[/tex] can be written as the sum of two partial fractions as [tex]\frac{3x}{(x+4)(x - 3)} - \frac{4}{(x+4)(x-3)}[/tex].
What is a partial fraction?For the decomposition of a rational equation, partial fractions are used. Each component of an algebraic expression that is divided into a sum of two or more rational expressions is referred to as a partial fraction.
Given, A rational expression [tex]\frac{3x - 4}{x^2 + x - 12}[/tex].
Now, x² + x - 12 can be written as
x² + x - 12.
= x² + 4x - 3x - 12.
= x(x + 4) - 3(x + 4).
= (x + 4)(x - 3).
Therefore, [tex]\frac{3x - 4}{x^2 + x - 12} = \frac{3x - 4}{(x + 4)(x - 3)}}[/tex].
[tex]\frac{3x - 4}{x^2 + x - 12} = \frac{3x}{(x+4)(x - 3)} - \frac{4}{(x+4)(x-3)}[/tex].
