It would be —C— because the third side can’t be 10 or less or 18 or more (x is the third side), this is because the triangle wouldn’t be able to connect.
Example
————— (18)
———- (10)
———— (x)
X would have to be in between them to be able to make a triangle
600 centimeters !!! :))))
Answer:
Step-by-step explanation:
We need a system of equations here. The first equation is that 3L boxes + 5s boxes (L = large and s = small) = 88 kg so
3L + 5s = 88
12L + 2s = 235 according to the other information given.
Solve the first equation for either L or s. I'll solve for L, just because:
3L = 88 - 5s and
L = and sub that into the second equation for L:
and if you distribute the 12 into the parenthesis you'll simplify it down a bit to
352 - 20s + 2s = 235 and combine like terms:
-18s= -117 so
s = 6.5 kg and plug that in to solve for L:
L = and
L = 18.5 kg
Answer: x= -10
Step-by-step explanation:
-3/4*(x+2) = 6 /multiply both sides by (-4/3)
-4/3*(-3/4)*(x+2) = 6*(-4/3) /-4/3*(-3/4) = 1
x+2 = -24/3 /-24/3 = -8
x+2 =-8 /subtract 2 from both sides
x = -8-2
x = -10
Answer:
x = 1.8
Step-by-step explanation:
5x - - 5x makes 5x+5x which is equal to 10x
10x+21= 39
-21 -21
10x= 18
10x/10 = 18/10
x = 1.8
