X=4 because minus 5x from 7x then you get 8=2x divide by 2 on both sides and you get x=4

Answer:

\boxed{\sf d. \ \frac{a}{b}  =  \frac{10}{7}}

Step-by-step explanation:

\sf \implies \dfrac{a - b}{b}  =  \dfrac{3}{7}  \\  \\  \sf \implies  \frac{a}{b}  -  \frac{b}{b}  =  \frac{3}{7}  \\  \\  \sf \implies  \frac{a}{b}  - 1 =  \frac{3}{7}  \\  \\  \sf \implies  \frac{a}{b}  - 1 + 1 =  \frac{3}{7}  + 1 \\  \\  \sf \implies  \frac{a}{b}  =  \frac{3}{7}  + 1 \\  \\  \sf \implies  \frac{a}{b}  =  \frac{3}{7}  +  \frac{7}{7}  \\  \\  \sf \implies  \frac{a}{b}  =  \frac{3 + 7}{7}  \\  \\  \sf \implies  \frac{a}{b}  =  \frac{10}{7}

Help pls I don't know how to explain it ​
a_sh-v [17]

Answer: C

Step-by-step explanation:

On the left side, there are 2 triangles and 6 2's, so this equals 2x+12.

On the right side, there are 4 triangles and 2 2's, so this equals 4x+4.

Meaning 2x+12=4x+4.

12=2x+4

2x=8.

Bertha has $2400 more invested at 4% than she has at 5%. If her annual income from these two investments is $294, how much does
Oksana_A [137]
So
x (4%)
y (5%)
x=y+2400
0.04x+0.05y=294

Once you solve them, x=4600 and y=2200
so 4%= $4600
5%= $2200
