3x6=18
4x6=24
16x6=96
The second picture is 6 times bigger than the first so it's 1 to 6
Answer:
-27
Step-by-step explanation:
x+23−23=−4−23
x=−27
The sum of all edges is 108 cm.
There are two bases whose edges are all 8 cm; this gives us 8(4)+8(4) = 32+32=64.
There are 4 edges between bases that are 11 cm each; 11(4) = 44
Together, this gives us 64+44=108 cm.
Answer:
x = 7 and y = −2
(7, -2)
Step-by-step explanation:
x = 1 - 3y
3x + 3y = 15
Substitute −3y + 1 for x in 3x + 3y = 15:
3(1 - 3y) + 3y = 15
3 - 9y + 3y = 15
3 - 6y = 15
-3 -3
-6y = 12
/-6 /-6
y = -2
Now we solve for x. Substitute −2 for y in x = −3y + 1:
x = 1 - 3y
x = 1 + (-3)(-2)
x = 1 + 6
x = 7
Now we check our solution.
x = 1 - 3y
7 = 1 + (-3)(-2)
7 = 7 ✅
3x + 3y = 15
3(7) + 3(-2) = 15
21 - 6 = 15
15 = 15 ✅
Answer:
12 Years
Step-by-step explanation:
Simple interest is calculated as I = Prt, where P is the principal (amount of money invested), r = rate of interest written as decimal, and t = time
The amount started as P and incresed by Prt, so
P + Prt = 1007.78
616 + (616)(0.053)t = 1007.78
Now you need to solve for t:
Subtract 616 from both sides and simplify:
32.648t = 391.78
Divide both sides by 32.648:
t = 12
