Step-by-step explanation:
Angle Z = Angle R = 35 degrees
Angle Y = 180-70-35 = 180-105 = 75
35 & 75 degrees
Answer:
<u>Equation: 87 + 91 + 86 + x = 360</u>
<u>Solution: 264 + x = 360</u>
<u>x = 360 - 264</u>
<u>x = 96</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
First three Kelsea's test grades : 87, 91 and 86
2. What score must she get on her fourth test to receive at least an A- ?
Define variable: x that represents the grade needed by Kelsea on her fourth test to receive at least an A-
Equation: 87 + 91 + 86 + x = 360
Solution: 264 + x = 360
x = 360 - 264
x = 96
<u>Now you can understand if the previous work you did is correct</u>
Answer: 3/7
Step-by-step explanation:
There's 28 student total.
12/28 simplify to 3/7
It equals 3600 combinations
4(equals the types of cones/cup) x 3(the measures of each one) x 20 (ice cream flavors) x 15 (toppings) += 3600 combinations
