Question
Which expressions are less than 7/8? Choose all answers that apply:
a) 7/8 x 9/15
b) 7/8 x 3/4
c) 7/8 x 9/9
d) 7/8 x 4/3
Answer:
a) 7/8 x 9/15
b) 7/8 x 3/4
Step-by-step explanation:
We are asked to find which expression are least than 7/8
Solving 7/8 = 0.875
We would evaluate the given option one after the other.
a) 7/8 x 9/15
= 63/120 = 0.525
b) 7/8 x 3/4
= 21/32 = 0.65625
c) 7/8 x 9/9
= 7/8 × 1 = 7/8 = 0.875
d) 7/8 x 4/3
= 7/6 = 1.1666666667
Therefore, from the above calculation, the expressions are less than 7/8 are
option a) a) 7/8 x 9/15 and b) 7/8 x 3/4
If I am reading the question correctly it would come out to -6x+42 First do all the addition and squaring, then factor in that negative. You come out to -2x^3 +2x^3-4x-2x+25+5+9+3. The x^3's cancel, the -x's add to -6x, then all that other adds to 42.
The answer would be $2.12.
The equation for this problem would look like… 2 x 1.06.
The second expression uses the greatest common factor and the distributive property to rewrite the sum 60 + 24.
60, 24
60 = 2² × 3 × 5
24 = 2³ × 3
We take the highest common factors -
=> 2² × 3
=> 4 × 3
=> GCF: 12
Therefore, the correct factored expression would be 12(5 + 2), which matches the second expression. Hope this helped!
