Answer:
1.6 repeating or 1.67 if you're rounding
Step-by-step explanation:
"Product of" tells you to use multiplication of the two terms
"square of x" = x²
"seven" = ... the number... 7
Your equation (your answer for these problems) can take a few forms:
x² · 7
7 · x²
7(x²)
(x²)(7)
7x²
Firstly you multiply 5 with everything in the brackets on the left side of = . and than you put t on the left side and change sign (if it was + then its going to be -) and numbers on right side and do the same with signs. then just calculate the rest
5(5t +1) = 25t - 7
25t + 5 = 25t - 7
25t - 25t = -7 + 5
0=-2
the statement is false
Answer:
40
Step-by-step explanation:
6% of number = 6/100 × x = 6x/100 = 3x/50
Sum of the number and 6% of itself = 42.4
x + (3x/50) = 42.4
(50x+3x)/50 = 42.4
53x = 42.4 × 50
53x = 2120
x = 2120/53
x = 40
21/7 = 3 so then, 105/7 = x which is 15
