I think it would be a and f :)
Answer:
120+100+120+120+x+x+10=720 (given)
470+2x=720
2x=720-470
x=250/2
x=125
Step-by-step explanation:
Answer: D. a+2s=$22
a+3s=$28
Step-by-step explanation:
Let's take a look at our variables. They are a and s, the a standing for the cost of an adult ticket and the s standing for the cost of the student ticket. In both situations, only one adutl ticket was purchased, so we start off out equations with only an a. As for the student tickets, Alex buys 2 and Jen buys 3.
a+2s
a+3s
The whole point of writing this equation is to find the cost of the tickets, so we would both equal it to the amount they spent.
a+2s=$22
a+3s=$28
Answer:
Chocolate cones = x = 167 cones
Vanilla cones = y = 334 cones
Step-by-step explanation:
Let
The number of Chocolate cones = x
Vanilla cones = y
Ike's igloo sold 501 ice cream cones today.
x + y = 501.... Equation 1
They sold half as many chocolate ice cream cone as vanilla ones.
x = 1/2y
x = y/2
Cross multiply
y = 2x
We substitute 2x for y in Equation 1
x + 2x = 501
3x = 501
x = 501/3
x = 167
Solving for y
y = 2x
y = 2 × 167
y = 334
Therefore,
The number of
Chocolate cones = x = 167 cones
Vanilla cones = y = 334 cones
Answer:
<u>√21 + 3√2 - √35 - √30</u>
Step-by-step explanation:
<u>Given :-</u>
√3 - √5 / √7 - √6
<u>Solving :-</u>
= √3 - √5 (√7 + √6) / √7 - √6 (√7 + √6)
= √21 + √18 - √35 - √30 / 7 - 6
= √21 + 3√2 - √35 - √30
<u>Solution :-</u>
<u>√21 + 3√2 - √35 - √30</u>
