Answer:

<h3>            Jake is 13 years old</h3>

Step-by-step explanation:

D      - age of Dani

J = D+2    - age of Jake

E = 2J = 2(D+2) = 2D+4    - age od Ethan

Z = 2E = 2(2D+4) = 4D+8    - age of Zoe

The sum of their ages is 102:

     D  +  J  +  E  +  Z  = 102

D + D+2 + 2D+4 + 4D+8 = 102

     8D + 14 = 102

         -14          -14

      8D  =  88

      ÷8        ÷8

      D = 11

J = 11+2 = 13

Suppose 12% of the students chose to study French their freshman year, and that meant that there were 21 such students. How many
AleksAgata [21]

Answer:

154 students

Step-by-step explanation:

First get the total number of students .

This can be gotten by

12% of A = 21

Where A represents the total number of students.

12% represents the % of A that chose to study French and 21 is the number of students that studied French .

Therefore,

12% /100% x A = 21

0.12 x A = 21

Divide both sides by 0.12

0.12/0.12 x A = 21/0.12

A = 175

The total number of students is 175.

If 21 chose to study French their freshman year ,number of students that chose not to will be total number of students minus number of those who chose to study French.

That’s

175 - 21

= 154

154 students chose not to study French their freshman year

harina [27]
30/40 say no, so x/1000 would say no. 1000/40=25, 25*30=750. So, about 750 would dislike it.

NEED ASAP WILL GIVE BRAINLIEST Write a real world problem that can be represented by the following inequality, 15X - 20 ≤ 130 ,a
ddd [48]

Answer:

I used my name, lol

Step-by-step explanation:

Kat wants to use her money to support animals at a shelter after receiving her pay check from work . She pays $15 per animal, and leaves $20 for the workers. She can spend at most $130. How many animals can she help?

Solve for x

15x-20\leq 130

Add 20 to both sides to isolate x

15x-20+20\leq 130+20\\15x\leq 150

Divide each side by 15

\frac{15x}{15}\leq  \frac{150}{15} \\\\x\leq 10

Kat can help at most 10 animals.

(I am so sorry I took so long, I couldn't come up with anything.)
