Answer:
143.70 = 3(39.95) + x
where x is the additional fee spent to race the cars at the park
Step-by-step explanation:
Let’s write the complete question first before we solve;
Blake and two of her friends are going to an amusement park. The cost of admission to the park is $39.95 per person. Once they are in the park, Blake and her friends ride the race cars, which require an additional fee. The total amount spent by all three boys is $143.70. Write an equation that can be used to find the additional fee to ride the race cars.
solution;
we are trying to write an equation that could help determine the additional fee used to race cars at an amusement park by a group of friends.
we proceed as follows;
We identify that they are 3, with each spending an amount equal to $39.95 for admission.
now to find the additional fee, we simply multiply the admission fee by 3 and subtract from the total amount spent.
let’s say the additional fee is x
This means;
143.70 = 3(39.95) + x
To get x, we can then open the bracket then take the value to the other side to get x
Answer:
12
Step-by-step explanation:
since you already know that the short sides together are 4 inches, that means there's 18 inches left, so 9 inches for each long side. Add 3 to 9 and you have your unknown number.
8x - (5x + 4) ≥ -31
8x -5x - 4 ≥ -31
3x ≥ -31 + 4
3x ≥ -27
x ≥ - 9
Answer: a numbe line with a circle on - 9 and shading to the left.
Because that drawing represents the number that are less or equel than -9 and the answer is the numbers greater or equal than -9.
