X = 23
x + 4x = 115
5x = 115
115/5 = x
23 = x
hope it helps!

I believe to find the range you just subtract the smallest from the largest:6.3-3.2=3.2
Let f= number of five cent stamps
let t=number of ten cent stamps
total spent is 5f+10t=100
total stamps bought is f+t=13
5f+10t=100
f+t=13
f=13-t
5(13-t)+10t=100
65-5t+10t=100
5t=35
t=7
f+t=13
f+7=13
f=6
6 five cent stamps and 7 ten cent stamps
Answer:
44°
Step-by-step explanation:
Given:
m<DOC in circle O = 44°
m<COB in circle O = 80°
Required:
Measure of arc DC.
SOLUTION:
<DOC is a central angle that intercepts arc DC. Central angles are said to be congruent to the arc they intercept.
Therefore, m<DOC = measure of arc DC.
Since m<DOC = 44°, the measure of arc DC = 44°.
Arc DC = 44°
Y²/58² + x²/b² = 1
<span>(0,58), (-21,29), and (21,29) are points on the ellipse. </span>
<span>29²/58² + 21²/b² = 1 </span>
<span>¼ + 21²/b² = 1 </span>
<span>21²/b² = ¾ </span>
<span>4·21²/3 = b² </span>
<span>b² = 588 </span>
<span>y²/3364 + x²/588 = 1</span>
