Answer:
-6 mph
Step-by-step explanation:
45 is 3/4hour so -8 times 3/4= -24/4=-6mph
Answer:
and
Step-by-step explanation:
To solve this, you must set up a system of equations. The first sentence says that there are two numbers and that their sum is 91, so your first equation is . For the next equation, it says that the difference of those same numbers is 1, which means that the equation is . Now, putting those two together for the system of equations, it's easiest to add them. The result will be which when simplified gives you the value of x. Taking the value of x, you can substitute in the second equation to find the value of y.

Step-by-step explanation:
0.12 = 12/100
0.36 = 36/100
Adam's dad paid £52.20.
This is considered three "parts" of the total cost.
Let's divide by 3 to find the size of one part.
£52.20 ÷ 3 = £17.40
Now, multiply by 5 (Adam's parts + his dad's) to get the total cost.
Like terms are terms that have the same variable and power/exponent.
-4q - (-8q) + 10 (two negative signs cancel each other out and become positive)
-4q + 8q + 10 The only like terms you can combine are -4q and 8q, because they have the same variable of q and an exponent of 1.
4q + 10 (this is as far as you can simplify)
