The solution would be like
this for this specific problem:
a + 20 = 5/7 (3a - 20) <span>
a + 20 = (15a - 100)/7 </span><span>
Multiply both side by 7, </span><span>
7a + 140 = 15a - 100 </span><span>
8a = 240<span>
</span></span>a = 30
3a = 90
a + 20 = 50
3a - 20 = 70
<span>5/7 x 70 = 50</span>
The answer is 2.
3/2a - ab + 1
3/2(5/6) - 5/6(3/10) + 1
5/4 - 1/4 + 1
4/4 + 1
1 + 1 = 2
Answer:
The required expression would be 
Step-by-step explanation:
Since, the amount formula is,

Where,
P = invested amount,
t = number of periods,
r = rate per period,
Given,
The invested amount at month 1, P = 4,
Number of periods from month 1 to month 4, t = 3
Amount at the end of fourth month, A = 256.
By substituting the values,




Hence, the amount of money at the end of t months.

Kyle put "two" rectangles together to make this shape, so cut the shape into two. Then we know the bottom of one of the rectangles which is 16 is subtracted by 8 because half of 16 is 8 and 8 is one the measurements.


4(4m -3) + -1m(m + -5) = -52

4(-3 + 4m) + -1(m + -5) = -52
(-3 * 4 + 4m * 4) + -1(m + -5) = -52
(-12 + 16m) + -1(m + -5) = -52

-12 + 16m + -1(-5 + m) = -52
-12 + 16m + (-5 * -1 + m * -1) = -52
-12 + 16m + (5 + -1m) = -52

-12 + 5 + 16m + -1m = -52

-12 + 5 = -7
-7 + 16m + -1m = -52

16m + -1m = 15m
-7 + 15m = -52

-7 + 15m = -52
-7 + 7 + 15m = -52 + 7
-7 + 7 = 0
0 + 15m = -52 + 7
15m = -52 + 7

-52 + 7 = -45
15m = -45

15m ÷ 15 = -45 ÷ 15
m = -3

m = -3
