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
Number 15 is no solution.
Number 27 is that x has to be between -2 or 2.
This could be explained as -2≤x≤2
Sin D= opp./hyp. = 35/37
cos D= adj./hyp. = 12/37
tan D= opp./ adj. = 35/12
Number 5 would be D i think
Answer: 48
Step-by-step explanation:
From the question, we are informed that it takes 12 buckets of water to fill a fish tank. We are further told that Chloe uses scoops which are equal to 1/4 of a bucket.
The number of scoops that are needed to fill the whole tank would be:
= 12 ÷ 1/4
= 12 × 4
= 48
