Answer:
PR=8; ST=5
Step-by-step explanation:
Find PR:
PQ=PR
8=2x
x=4
PR=2x=2(4)=8
Find ST:
TU=ST
2z+3=5z
3=3z
z=1
ST=5z=5(1)=5
Answer:
56.6in³
Step-by-step explanation:
volume of a pyramid = 1/3 x Area of base x height
1/3 x 11.1 x 15.3 = 56.61 in³
56.6 in³ to the nearest tenth
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
the hundredth term is 1 which is less than 5. O is added to 6
ANSWER:
9/x-1
EXPLANATION:
The Denominator won’t change because they are already the same. However, you have to subtract the numerator.
WORKING OUT:
Denominators)
Bases stay the same so no need for any changes
=x-1
Numerators)
(x+1)-(x-8)
Put the variables to get her and the number together.
(x-x)+(1-(-8))
(0)+(9)
=9
9/x-1
