Answer:
Step-by-step explanation:
-x+10=6
-x=6-10
-x=-4
x=4
<span>(-4s)(2s³)
We're multiplying two monomials. Multiplying the numerical values first, (-4)(2), would give us -8. To multiply the s values, (s)(s</span>³), we just have to add the exponents. Keep in mind that
. Adding the exponents of the variable s gives us
. Our answer is
.
Answer:
It will take 1.5 hours to paint the room together
Step-by-step explanation:
Martha can paint a room in 2 hours. Jamie can paint the same room in 6 hours.
Work done by Martha in 1 hour =
Work done by Jamie in 1 hour =
Work one together in 1 hour =
Now take common denominator to add both fractions
LCD = 6, Multiply the first fraction by 3
Now add the numerators
To find total hours of painting together, we take reciprocal of 2/3
Time taken to paint together =
It will take 1.5 hours to paint the room together

Answer: By cross multiplication.
Step-by-step explanation: Given product is 3 × 292.
We know that after simple multiplication, we get 3 × 292 = 876.
Now, to check division with multiplication, either we need to divide 876 by 3 to get the answer 292,
or
we need to divide 876 by 292 to get the answer 3.
We will do that as follows -
Thus, doing cross-multiplication, we arrive at our conclusion.
