Answer:
Emilia bought 28 sweets
Step-by-step explanation:
now they have 65, but before they had 65-15+10 because earlier, zakiah had ten more sweets than now and Emilia had 15 less, so basically, if you wanna calculate number of sweets they had earlier, you have to make minus from plus and in reverse too.
65-15+10=60 and now just do that simply ratio
E:Z=7:8
E+Z=7x+8x
60=15x
4=x
7x=28=Emilia
8x=32=Zakiah
Accuracy test:
(28+15)+(32-10)=65
28 is 4•7 and 32 is 4•8
Answer:
A=2pi(9) I think
Step-by-step explanation:
Answer:
V = 300
in³ or 942.48 in³
Step-by-step explanation:
Use the cylinder volume formula, V = r²h, where r is the radius and h is the height.
Plug in the values and solve:
V = (5²)(12)
V = 300 in³ or 942.48 in³
Slope intercept is y = mx + b
b is 1470
2x + 3y = 1470
2x (-2x) +3y = 1470 - 2x
3y = -2x + 1470
3y/3 = (-2x + 1470)/3
y = -2/3x + 490
hope this helps
