Shakira went bowling with her friend.She paid$3 to rent shoes and then$ 4.75 for each game of bowling if she spend a total of $42 then how many games did shakira bowl.
Answers
Given
She paid $3 to rent shoes and $ 4.75 for each game of bowling.
she spend a total of $42
How many games did shakira bowl.
To proof
let the number of games shakira did bowl = x
paid $3 to rent shoes and $ 4.75 for each game of bowling
she spend a total = $42
Than the equation is become in the form
4.75x = 42 - 3
4.75 x = 39
x = 8.21(approx)
therefore 8 games did shakira bowl.
Hence proved

1 day = 24 hours = 24 x 3600 = 86400 seconds
1 day ...... 86400 seconds
365 days ..... t seconds
t= 365 x 86400 /1 = 31536000
So, we have 31536000 seconds in 365 days. => 31536000 seconds = 1 year
--------------------------------------------------------------
1 year ........ 31536000 seconds
15 years .......... z seconds
z = 15 x 31536000 / 1
z= 473040000
So, 15 years = 473040000 seconds !!!!!!
Done.

a=20(5)+30
20*5=100
100+30=130
Altitude: 130 yards.
Final answer:
The balloon's altitude increases by 5 yards each minute. So, after 20 minutes, the balloon has ascended 100 additional yards. If it was initially 30 yards above the ground, it is now at an altitude of 130 yards.
Explanation:
Based on the provided information, the altitude of the balloon changes at a rate of 5 yards per minute. At the beginning, the balloon is 30 yards above the ground. This initial altitude is increased by the amount of change happening every minute. Therefore, after 20 minutes of continuous upward movement, the change in altitude is 20 minutes * 5 yards/minute = 100 yards. Thus, the final altitude of the balloon becomes the sum of its initial altitude and the change, which is 30 yards + 100 yards = 130 yards.

Answer:
Hi! The correct answer is (-2,-1)!
Step-by-step explanation:
~Add the equations in order to solve for the first variable, Plug this value into the other equations in order to solve for the remaining variables~
Second equation: 3x - 9y = 30
The first equation should be multiplied by 3 and the second equation by 5.
The first equation should be multiplied by 3 and the second equation by −5.
The first equation should be multiplied by 9 and the second equation by 4.
The first equation should be multiplied by 9 and the second equation by −4.
Answers
9(5x - 4y) = 9(28)
4(3x - 9y) = 4(30)
45x - 36y = 252 ⇒ 45x - 36y = 252
-(12x - 36y = 120)⇒ -12x + 36y = -120
33x + 0 = 132
33x = 132
x = 132/33
x = 4
5x - 4y = 28
5(4) - 4y = 28
20 - 4y = 28
-4y = 28 - 20
-4y = 8
y = 8/-4
y = -2
x = 4 ; y = -2
3x - 9y = 30
3(4) - 9(-2) = 30
12 + 18 = 30
30 = 30
