Answer:
x = 1.5
Step-by-step explanation:
We need a value of x that would result in 2x+9 = 12
2x+9 = 12
2x = 12 - 9
2x = 3
x = 3/2 or 1.5
====
CHECK
Does 2x+9 = 12 when x = 1.5?
2x+9 = 12
2(1.5)+9 = 12
3 + 9 = 12 YES
Answer:
Step-by-step explanation:
Let base be b, height be h
h = 7+b or we can say that b = h -7
A = 15 cm²
General formula for area of a triangle
A = b · h
Substitute what we know to find the height h
15 = (h-7) · h
15 = h² -7h
0 = h²-7h -15
h = (7 ±√49 + 4·1·15)/2
h = (7 ±√109)/2
h ≈ -1.72 reject this solution because height cannot be negative
h ≈ 8.72 cm
This question is asking us to add the numbers together to create the sum of drinks.
210 + 195 = 405
Why tho?
1 : 0 + 5 = 5
2 : 1 + 9 = 10 Carry the one.
3 : 2 + 1 = 3 + 1 = 4
=405
Hope helps!-Aparri
Because these two lines have the same slope, they are parallel. Since they are parallel, they never intersect and therefore have no solutions, so the answer is C
18,19 and 20 are the integers.
Step-by-step explanation:
Given three integers are;
n, n+1, n+2
According to given statement;
n+(n+1)+(n+2)=57
n=18
n+1 = 18+1 = 19
n+2 = 18+2 = 20
18,19 and 20 are the integers.
