Step-by-step explanation:
80+60+x+51= 180
191+x= 180
x= -11
Answer:
The first one 24/4
Step-by-step explanation:
Into usually means divide when it's used as a math term,
therefore 24 into fourths means 24 divide by 4.
We can solve this system using elimination:
(x+y=24)3
3x+5y=100
3x+3y=72
-(3x+5y=100)
0x-2y=-28
y=14
We can then plug this back into one of the original equations:
x+14=24
x=10
We can check our answer by plugging this into both of the original equations:
10+14=24
24=24
3(10) + 5(14)=100
30+70=100
100=100
Therefore, there are 10 3-point questions and 14 5-point questions.
The answer is B (-3).
-2+3n>-14
+2 +2
3n>-12
n>-4
Answer:
a. the ratio is 1:2
b. its equivalent to the fraction 1/2
c. there would be 10 triangles
d. therw would be 45 triangles since the number of parallelograms is double the number of triangles
