Answer:
1/10
Step-by-step explanation:
add 2/5 and 1/2 then subtract from 1 whole to find the remainder
make it so they have the same denominator
2/5 = 4/10
1/2 = 5/10
4/10 + 5/10 = 9/10
1=10/10
10/10-9/10 = 1/10
so 1/10 of the students don't exercise at all
double bracket factorisation
2 × 15 = 30
find two factors of 30 that add to give -7
(-10, +3)
2x^2 -10x + 3x - 15
2x(x-5) + 3 (x-5)
<em><u>(</u></em><em><u>2x</u></em><em><u>+</u></em><em><u>3</u></em><em><u>)</u></em><em><u> </u></em><em><u>(</u></em><em><u>x-5</u></em><em><u>)</u></em>
<em><u>THE</u></em><em><u> </u></em><em><u>ANSWER</u></em><em><u> </u></em><em><u>IS</u></em><em><u> </u></em><em><u>X-5</u></em>
Answer:
Step-by-step explanation:
kira spent: 15 h TV/12 h Read so the ratio is 15/12=5/4
charlie had a ratio of 20/16=5/4
choice C , ratios are equal
Answer:
c) 28
explanation :
In this sequence:
a1 = 2
a2 = 4
a3 = 6
a4 = 8
a5 = 10
and so on...
then
the sum from a2 to a5 is:
a2 +a3 + a4 + a5 = 4 + 6 +8 + 10 = 28
