8.66, you divide 12.99 into 3 and then multiply the result which is 4.33 by 2
Answer:
95%
Step-by-step explanation:
0.6 of 40 is 24, she bought 24 green balloons.
24 × 1.5 = 36, she bought 36 yellow balloons.
So we have
40 red
24 green
36 yellow
Then from the rest of the information, 2 red, 2 green, and 1 yellow balloon all popped.
We now have
38 red
22 green
35 yellow
for a total of:
95 balloons out of 100 original balloons, 95%
Answer:
A=l•w
A=6•10
A=60 yards square
1 yr sq 4$
60 yr sq x$
x=60•4/1
x=240 $
It would cost 240$ to carpet the room
Step-by-step explanation:
Answer:
23
Step-by-step explanation:
sin theta = opp /hyp
sin H = 5/13
Take the inverse sin of each side
sin ^-1 (sin H) = sin ^-1 (5/13)
H =22.62 degrees
To the nearest degree
H = 23 degrees
Answer:
x = 7
y = 0
Step-by-step explanation:
Equation: 2x - 9y = 14
We are given that x = -6y + 7
So we substitute (-6y + 7) for "x" in the equation 2x - 9y = 14
* substitute *
2 ( -6y + 7 ) - 9y = 14
now we solve for y using basic algebra
step 1 distribute the 2
2 * -6y = -12y
2 * 7 = 14
now we have -12y + 14 - 9y = 14
step 2 combine like terms
-12y - 9y = -21y
now we have -21y + 14 = 14
step 3 subtract 14 from each side
14 - 14 cancels out
14 -14 = 0
now we have -21y = 0
step 4 divide each side by -21
-21y / -21 = y
0 / -21 = 0
we're left with y = 0
now to find x
To find x we substitute 0 for "y" in x = -6y + 7
* substitute *
x = -6 ( 0 ) + 7
-6 * 0 = 0
we're left with x = 7
