2x+7=27 and 3x+1=28 does 2x+7= 3x+1
Savatey [412]
Hey there!

2x + 7 = 27
2x = 20
x = 10

3x + 1 = 28
3x = 27
x = 9

The values for both of these equations are 9 and 10; therefore, the answers are not equivalent.

I hope this helps!

Are 12/7 and 36/21 proportional
anastassius [24]

Answer:

Step-by-step explanation:

Cross multiply:

12 * 21 = 7 * 36

Simplifying

12 * 21 = 7 * 36

Multiply 12 * 21

252 = 7 * 36

Multiply 7 * 36

252 = 252

Add '-252' to each side of the equation.

252 + -252 = 252 + -252

Combine like terms: 252 + -252 = 0

0 = 252 + -252

Combine like terms: 252 + -252 = 0

0 = 0

Solving

0 = 0

Couldn't find a variable to solve for.

This equation is an identity, all real numbers are solutions.

(hope this helps can i plz have brainlist :D hehe)

the problem is kamala had 5,026 grams  flour in a canister.she brought a 4,158 gram bag of flour.she poured some flour from the
andrey2020 [161]
Hello, 

x= amount of flour that she poured in the canister

there was 5,026 grams of flour, and now: 5,026+x

In the bag there was 4,158, now: 4,158

I says that as a result the mass of the flour in the canister is twice the mass of the flour left in the bag, so:

5,026+x=2*(4,158-x) \\ 5,026+x=8,316-2x \\ 3x=8,316-5,026 \\ 3x=3,290 \\ x=1,096.67

So, she poured 1,096.67 grams, we subtract this from the initial amount in the bag and we have the answer:

4,158g-1,096.67=\boxed{3,061.33}

Answer: there is 3,061.33 grams of flour in the bag
