Answering part A:
5x + -3x 7y + 3y + 2y 4xy doesn't have a like term
Step-by-step explanation:
like terms are when in an equation they might have variables that match like 4y + 7y they have the same variable which is y or 6 + 7 they don't have a variable at all but they are similar in that way. Btw why it says -3x is because I changed the equation to be all addition so I did kcc you don't have to do that if you find a different solution :) anyway lets move on to part b
Answering part B:
4xy + 2x −2y

Please help me. I'm struggling with my math
Answer:
a. (4, -3)
b. (-2.5, -4)
Step-by-step explanation:
a. 2x - 4y = 20
x = 4
step 1: plug in x value
2(4) - 4y = 20
8 - 4y = 20
Subtract 8 on both sides
-4y = 12
divide both sides by -4
y = -3
b. y = 6x + 11
2x - 3y = 7
step 1: plug in the y value
2x - 3(6x + 11) = 7
step 2: distribute
2x - 18x - 33 = 7
add 33 from both sides and combine like terms
-16x = 40
divide both sides by -16
x = -2.5
Okay now you plug in the x value to solve for y
y = 6(-2.5) + 11
y =-4

Answer:
Table 2
Step-by-step explanation:
We can solve this by dividing the number of pizzas at each table by the number of kids at each table. This will tell us how much pizza each kid is able to eat:
Table 1:
2 pizzas/5 kids = 2/5 pizzas per kid = 0.4 pizzas per kid
Table 2:
3 pizzas/7 kids = 3/7 pizzas per kid = 0.429 pizzas per kid
Table 3:
5 pizzas/12 kids = 5/12 pizzas per kid = 0.417 pizzas per kid
The kids at table 2 are able to eat slightly more pizza than the kids at the other tables.

10 to the power of -2 as a fraction
Answer:
Step-by-step explanation:
10 to the power of -1 = 0.1
10 to the power of -2 = 0.01
0.01 as a fraction =
1/10000
because
10 = 1/10 or 10/100
1= 1/100
0.1 = 1/1000
0.01 - 1/10000
Answer:
1/100
Step-by-step explanation:
10^2 is 100 so 10^-2 would be 0.01 or 1/100

There are four consecutive integers that add up to 22 what is the greatest integer
Answer:
7
Step-by-step explanation:
We can use the equation:
x + (x + 1) + (x + 2) + (x + 3) = 22
Combine like terms
4x + 6 = 22
Subtract 6 from both sides
4x = 16
Isolate x
x = 4
Plug in x
4 + (4 + 1) + (4 + 2) + (4 + 3) = 22
Solve
4 + 5 + 6 + 7 = 22
7 is the greatest integer

a) Keith's car will have less gas.
Locate the point in which miles driven = 90 (Between 60 and 120)
Since Keith's line is lower than Carmen, he has less gas.
We can also find the difference: 11 - 10 = 1.
It will have 1 less gallon.
b) Look at the point in which both lines meet. This means that they have the same amount of gallons remaining (8) at 180 miles driven.
Before 180 miles, Keith's car will always have less car remaining.

Find the constant of proportionality and write an equation for the following proportional relationship.
You can buy 14 apples for $28.
Use a to represent number of apples and c to represent the cost
Answers:
constant of proportionality: 2equation is: c = 2a==================================================
Explanation:
a = number of apples purchased
c = cost in dollars
The equation is in the form c = ka, where k is the constant of proportionality. It tells us what to multiply 'a' by to get the cost c. In more realistic practical terms, the value of k is the cost per apple (aka unit cost).
To find this unit price, we divide the given price by the given number of apples: k = c/a = 28/14 = 2. Each apple is $2. The constant of proportionality is 2.
We'll update the equation from c = ka to c = 2a
Note that if we bought a = 14 apples, then it costs us c = 2a = 2*14 = 28 dollars as expected.
Answer:
c=2a
Step-by-step explanation:
c=2a

Answer:
x = -9, 4
Step-by-step explanation:
The sides are marked congruent, so you have ...
x^2 +5x = 36
Subtracting 36 puts this in standard form:
x^2 +5x -36 = 0
To factor this, you need to find factors of -36 that have a sum of 5.
-36 = (-1)(36) = (-2)(18) = (-3)(12) = (-4)(9) = (-6)(6)
The sums of these factor pairs are 35, 16, 9, 5, 0.
The pair with a sum of 5 is (-4)(9), so the factorization of the quadratic is ...
(x -4)(x +9) = 0
The solutions are the values of x that make the factors zero:
x = 4, x = -9
Both of these solutions work in this problem.
there are 15 pieces of fruit in a bowl and 6 of them are oranges.what is the percenage of fruits are in oranges
Hi there!
We can find the percentage by expressing the amount of oranges to total fruits as a fraction:
[tex]\text{ oranges to total fruit} = \frac{\text{x Oranges}}{\text{ y total pieces of fruit}}[/tex]
Plug in the given values:
[tex]\text{ oranges : total fruit} = \frac{\text{6}}{\text{15}} = 0.4[/tex]
Convert to a percentage by multiplying by 100:
0.4 × 100 = 40%.
[tex]\boxed{\text{40\% of total pieces of fruit are oranges}}[/tex]

Solve for m.
13m – 34m + 42m - 22m + 8 = -41
Answer:
m=14
Correct me if I'm wrong ^•^
Answer:
m = -49
Explanation:
Combine like terms
13m - 34m + 42m - 22m + 8 = -41
-m + 8 = -41
Subtract 8 from both sides of the equation
-m + 8 = -41
-m + 8-8 = -41 -8
Simplify
Subtract the numbers
-m = -49

Will mark brainliest
Answer:
1+1=2
1+1−52=2−52
(1+1−52)2=(2−52)2
(1+1−52)2=22−10+(52)2
(1+1−52)2=4−10+(52)2
(1+1−52)2=9–15+(52)2
(1+1−52)2=32–15+(52)2
(1+1−52)2=(3−52)2
1+1−52=3−52
1+1=3
need help please and thank you!!
Answer:
x=125
Step-by-step explanation:
Since the sum of the angles is 720 degrees, you can set up the following equation:
120+100+120+120+x+(x+10)=720
2x+470=720
2x=250
x=125
