Answer:
The coach paid $69 on the three soccer balls
Step-by-step explanation:
If the coach bought 3 soccer balls for 26$, minus the $7 on each, plus the $4 tax on each, the expression would be:
3 × (26 - 7 + 4)
We put the addition and subtraction in parentheses because of PEMDAS. PEMDAS say we must solve for whatever is in the parentheses first, then exponents (there are none in the expression), ans then multiplication. If those numbers were not in parentheses, the answer would look completely different as we would multiply before subtracting and adding. We must find the total amount each ball cost first:
26 - 7 + 4 = 23
Each ball cost $23
If the coach bought 3 balls for $23 each, we have to multiply the two numbers:
3 × $23
$69
Answer:
D. Both a relation & a function.
Step-by-step explanation:
A relation is a set of one or more ordered pairs. A function is a relation in which each input has exactly one output. A set of ordered pairs represents a function if, for every value of x, there is only one value of y. In the given situation, the x-coordinate is the number of weeks since she starts recording and the y-coordinate is the number of books read per week. It can be seen from the given set that each x-value corresponds with exactly one y-value. Therefore, the set of ordered pairs is best described as both a relation and a function.
Answer:
32/40, 4/5
Step-by-step explanation:
All these ratios are follow the ratio 4:5 meaning they are equivalent to "64:80".
8:12=0.666667
16"24=0.666667
120:160=0.75
Hi love...
The correct answer after solving for d is D=78. That’s a quick answer, but I can give you steps on how to solve.
1. Simplify both sides of the equation
2. Isolate the variable
3. Simplify
Then you’d have the answer!
Please let me know if you need further assistance! Have a jolly evening.
