Answer:
4 (9+4)
Step-by-step explanation:
its 4(9+4) because we are trying to make 36+16
4(8+5) is the same answer but it would be 32+20
while 4(9+4) would be 36+16
Option B model shows the percent of beads that are blue.
Solution:
Fraction of beads blue = 
To convert it into percent multiply the fraction by 100.
Cancel the common factors, we get
= 20%
This means total number of boxes 100 and shaded in blue color 20.
Therefore option 2 represents 
.
Hence option B model shows the percent of beads that are blue.
Answer:
d. 8
Step-by-step explanation:
Given: -3x + 2y = 1 and x = 5
Now plug x =5 in the given equation and find the value of y.
-3(5) + 2y = 1
-15 + 2y = 1
2y = 1 + 15
2y = 16
Dividing both sides by 2, we get
y = 8
Thank you.
Answer:
the product of 2 and 9 — 3rd choice
the difference of 2 and 9 — 2nd choice
the square of 9 — 1st choice
the sum of 2 and 9 — 5th choice
the quotient of 2 and 9 — 4th choice
Step-by-step explanation:
To solve a square root, get the ^2 on one side and the 81 on the other side.
add 81 to both sides.
c^2 = 81
to clear the power of 2, take the square root of both sides.
c = + - sqrt81
c = + - 9
c = 9 and c = -9
