Answer:
f = -5, s = -6
Step-by-step explanation:
F= first number
S= second number
4f - s = -14
f + 3s = -23
3(4f - s = -14)
12f - 3s = -42
+ f + 3s = -23
13f = -65
————
13
f = -5
4f - s = -14
4(-5) - s = -14
-20 - s = -14
+20 +20
-s = 6
———
-1
s = -6
Answer:
The answer is 10.5 or 10 1/2
Step-by-step explanation:
1) A=LxW
2) the height is given but you do not have the width So Divide.

H= 12 1/4= 12.25
A= 128 5/8= 128.625
4) 128.625 divided by 12.25 Give you 10.5
5) you can change 10.5 into a fraction 10 1/2
hopes this helps.
Answer:
The interval estimate is above 70%, so infer that it will be supported.
Step-by-step explanation:
The evidence that 95% confidence interval estimating the proportion of students supporting the fee increase is [0.75, 0.85] supports university officials' claim that at least 70% of the voting student population supports a fee increase.
Therefore we can infer that a fee increase will be supported.
Area of a triangle: (b*h) /2
So :
(14,5 * 10.5) /2
=152,25 /2
= 76.125

Step-by-step explanation:
Words Expression
The Value of the Expression
a. 50 times the sum of 64 and 36
... 50 x (64+36) = 50x (100) = 5000
50 x 64 + 36 )
5000
b. Divide the difference between 1,200 and 700 by 5
...(1200-700) / 5 = 500/5 = 100
(1,200 - 700): 5
100
C. The sum of 3 fifteens and 17 fifteens
... 
+ 
= 
= 
45 + 255
d. 15 times the sum of 14 and 6
... 15 x (14 + 6) = 15 (20) = 300
e.
10 x (250 +45)
...10 times the sum of 250 and 45
f.
(560 + 440) x 14... 14 times the sum of 560 and 440
Hope this helps
