Answer:
$5
Step-by-step explanation:
25 = 4e + 5
20 = 4e
5 = e
reach eraser costs $5.
Please, enclose those binomials x+4 and y+7 inside parentheses:
(x+4) / 4 = (y+7) / 7. Find (x/4).
Let's solve the above equation for x:
x+4 = 4(y+7)/7. Then x = 4(y+7) / 7 - 4
Last, divide all 3 terms by 4: x/4 = (y+7) / 7 - 1 (answer)
y + 7 - 7
You could also type this as x/4 = ------------- = y/7
7
Answer:
Is there anyway you can explain it more?
Answer:
Neither of them has partitioned the values correctly. The answer to the sum 3568 × 39610 =141 328 480.
They tried the partition method but did not partitioned it correctly.
3568 = 3000+500+60+8
39610 = 30000+9000+600+10
Now multiply each value of 3568 with the values of 39610. Like:
3000 * 30000
3000 * 9000
3000 * 600
3000 * 8
and so on....
Step-by-step explanation:
Let's separate this problem into several parts:
1. The product of x
AND
2. The sum of 6 and 8
TIMES
3. The square of x
So translating this word problem into numbers, we have:
x TIMES (6+8) TIMES x²
so that is:
x * 14 * x²
which is:
14x^(2+1) = 14x³
