A.
If:
j - the price of a glass of juice
p - the price of a pancake special
Then:
3j + 5p = 7.60
j + 2p = 2.90
b.
If:
j + 2p = 2.90
Then:
j = 2.90 - 2p
We can substite j in the first equation.
<span>If:
3j + 5p = 7.60
</span><span>j = 2.90 - 2p
</span>Then:
3×(2.90-2p) + 5p = 7.60
8.70 - 6p + 5p = 7.60
8.70 - p = 7.60
⇒ p = 8.70 - 7.60
⇒ p = 1.10
If:
<span>j = 2.90 - 2p
</span><span>p = 1.10
</span>Then:
j = 2.90 - 2×1.10
j = 2.90 - 2.20
j = 0.70
Thus, the price of a glass of juice is $0.70 and <span>the price of a pancake special is $1.10.
c.
If:
p = 1.10
j = 0.70
Then:
j + p = 1.10 + 0.70 = 1.80
Thus, </span><span>the bill for 1 glass of orange juice and 1 pancake special is $1.80.</span>

The measure of <YXP and <YZQ are 35 and 65 degrees respectively
<h3>Equilateral triangles</h3>
Equilateral triangles are triangles that has equal sides and angles.
From the given diagram;
<YZQ + 90 + 25 = 180
<YZQ =180 -115
<YZQ = 65degrees
Determine the measure of <YXP
<YXP = 60 - 25 (XYZ is a 60degrees triangle)
<YXP = 35 degrees
Hence the measure of <YXP and <YZQ are 35 and 65 degrees respectively
