Answer:
Step-by-step explanation:
The equivalent value of given the expression is -17.25. Therefore, option C is the correct answer.
<h3>What is an equivalent expression?</h3>
Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.
The given expression is -14-8×0.5+0.75.
Now, -14-8×0.5+0.75
= -14-(8×0.5)+0.75
= -14-4+0.75
= -18+0.75
= -17.25
The equivalent value of given the expression is -17.25. Therefore, option C is the correct answer.

Answer:
Step-by-step explanation:Answer:
1cm = 50
2 cm = 50 x 2
3cm = 50 x 3
and the inverse:50m = 50/50 = 1cm
100m = 100/50 = 2cm
150m = 150/50 = 3cm
381m = 381/
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!
