Answer:
D
Step-by-step explanation:
Product means multiplication. Since we are multiplying 6s to (-2s²+4s-10), we will use the distributive property to solve.
6s(-2s² + 4s - 10)
-12s³ + 24² - 60
Best of Luck!
Answer: 1875km 840m
Step-by-step explanation:
From the question, we are informed that Gupty travelled 75km 800m by car and travelled 1800km 40m by aeroplane.
The distance that she travel altogether will then be:
= 75km 800m + 1800km 40m
= 1875km 840m
Answer:
D or y-25=2(x-10)
Step-by-step explanation:
If you graph all or the answers the only one that hits both points is D.
X=number of boys
y=number of girls.
We can suggest the following system of equations:
x+y=33
x/y=3/8
We solve this system of equations by substitution method.
x/y=3/8 ⇒x=3y/8
(3y/8)+y=33
least common multiple=8
3y+8y=33*8
11y=33*8
y=(33*8)/11
y=3*8
y=24
x+y=33
x+24=33
x=33-24
x=9
number of boys /total number of students=9/33=3/11
There are 9 boys and 24 girls in the class.
Answer: C: 9. since 3/11 of the students are boys.
