<span>What is the simplified form of the expression 7[63÷(5^2-2^2)-1]?
</span>7[63÷(5^2-2^2)-1]
= 7[63÷(25-4)-1]
= 7[63÷(21)-1]
= 7[3-1]
= 7 (2)
= 14
answer is <span>C. 14
</span><span>Which is a solution of the equation y=4x+3?
answer is
C. (4,19)
</span>y=4x + 3
19 = 4(4) +3
19 = 16 +3
19 = 19
Add 3.26d+9.75-2.65
13.01y - 2.65
Well, if 24 is 4% of a number, then you need to work out what 100% is.
The formula is 100/4 i.e. 100% divided by 4%= 25
25 x 24 = 600
