Answer:
The cost of one cup of hot chocolate is $4.50
Step-by-step explanation:
Let
x ----> the cost of one cup of hot chocolate
y ----> the cost of one cup of hot tea
we know that
3x+4y=25.50 ------> equation A
y=(2/3)x -----> equation B
Solve the system of equations by substitution
substitute equation B in equation A and solve for x
3x+4(2/3)x=25.50
3x+(8/3)x=25.50
(17/3)x=25.50
x=25.50*3/17
x=$4.50
therefore
The cost of one cup of hot chocolate is $4.50
Answer:4 answer
Step-by-step explanation:
Answer:
a
Step-by-step explanation:
8 + 8 = 16
40 - 16 = 24
16 x 2.5 = 40
2.5 rounded = 3
Tangent 45 = height / 3
height = 3 * tan (45)
height = 3 * 1
height = 3
<span>Trapezoid area = ((sum of the bases) ÷ 2) • height
</span>
<span>Trapezoid area = (9 + 15) /2 * height
</span><span>Trapezoid area = 12 * 3
</span><span>Trapezoid area = 36
</span>
