Answer:
there are fourteen 4-point questions and twenty six 2-point questions.
Step-by-step explanation:
Given : A 40-question test has 108 possible points.
There are m 4-point questions and n 2-point questions.
So , equation for total number of questions in the test :
m + n = 40 | 4n + 2n = 108
Multiplying (i) by 2 , we get
2m + 2n = 80
Subtract (iii) from (ii) , we get
2m = 28
⇒ m = 28/ 2 = 14
Using value of m in (i) , we get
14 + n = 40 ⇒ n = 26
from this we get there are fourteen 4-point questions and twenty six 2-point questions.
hope this helped!
Answer:
x = -4 x = 3
Step-by-step explanation:
To find the x intercepts, set y =0
(x+4) (-x+3) =0
Using the zero product property
x+4 =0 -x+3 =0
x = -4 x = 3
Answer:
This is called transitivity property

Answer:
BAKING TINS
Step-by-step explanation:
Use the Pythagorean Theorem to solve = 
.
2) 8² + 6² = c²
64 + 36 = 100
x = 10 = I
3) 10² - 9² = a²
100 - 81 = 19
x = 4.4 = G
4) 8.8² + 3.2² = c²
77.44 + 10.24 = 87.9
x = 9.4 = B
5) 27² - 24² = a²
729 - 576 = 153
x = 12.4 = S
6) 11² - 7² = a²
121 - 49 = 72
= 8.5
13² + 8.5² = c²
169 + 72.25 = 241.25
x = 15.5 = T
7) 22.1² + 14.2² = c²
488.41 + 201.64 = 690.1
x = 26.3 = K
8) 32² + 41² = c²
1024 + 1681 = 2705
x = 52 = N
Hope it helps!
