Effectus [21]3 years ago
6 0

Step-by-step explanation:

I think it is meant to use "j" for Jahiem's age.

so,

j + s = 21

j = s + 7

=> s + s + 7 = 21

=> 2s + 7 = 21

=> 2s = 14

=> s = 7

=> j = s + 7 = 7 + 7 = 14

Please help!!! I will give brainliest but only if you try and help.
Slav-nsk [51]

Answer:

<h2>____</h2><h3>1260 </h3><h2>____</h2>

Since we have to predict, we can use ratios to help us solve this.

12 said yes out of 72 randomly chosen, SO,

if 210 would say yes (goes to play), how many is total??

12 is to 72 AS 210 is to HOW MUCH (let it be x)??

We can setup ratio, cross multiply, and solve for x:

= 12/72= 210/x

= 12x = 210*72

=12x = 15,120

=x = 15,120/12

<h2>=x =1260</h2>

Solve for e.<br><br> 4/3=-6e-5/3
cricket20 [7]

Answer:

e = 1/2

Step-by-step explanation:

to solve foe e in  this 4/3=-6e-5/3

solution

4/3=-6e-5/3

4/3 + 5/3 = 6e

find the lcm of the left hand side

4 + 5/3 = 6e

9/3 = 6e

cross multiply

3 x 6e = 9 x 1

18e = 9

divide both sides by the coefficient of e which is 18

18e /18 = 9/18

e = 1/2

therefore the value of e in the expression above is evaluated to be equals to 1/2
