Answer:
22
Step-by-step explanation:
2x-7(y+1)
-7(-3+1)=14
2*4=8
8+14 is 22
So 20% of 22.58
'of' can be translateed as multiply
20% means 20 parts ouf of 100 or 20/100=2/10=0.20
so 0.2 times 22.58=4.516 or round up to
he sould leave a tip of $4.52
Answer:
y = -5 and x = -17
Step-by-step explanation:
We want to solve these two equations,
x = 3y - 2
x = 5y + 8
We can see that they both equal x so we want make them equal to each other so,
→ 3y - 2 = 5y + 8
⇒ Subtract 5y from both sides to collect the 'y' terms
→ -2y - 2 = 8
⇒ Add 2 both sides to collect the numerical terms
→ -2y = 10
⇒ Divide both sides by -2 to isolate y
→ y = -5
Now that we have found the value of y we can substitute this value into one of the 2 equations we have to find the value of x
⇒ We know that y = -5 so lets substitute that into x = 3y - 2
→ x = 3 × -5 - 2
⇒ Simplify
→ x = -15 - 2
⇒ Simplify further
→ x = - 17
The total distance traveled in 2-hour time is 50 miles. (option g)
Shauna drove 75 miles in 3 hours at a constant speed, so the total distance covered in 3 hours is 75 miles to find the distance covered in 2 hours, we first need to find the distance or miles covered in 1 hour
To find the distance Shauna traveled in 2 hours, use the following formula: –
Speed = distance/time
Total distance traveled = 75 miles
Total time = 3 hours = 3 hours
Speed = 75/3
Speed = 25 miles per hour
Distance traveled in 2-hour time is 50 miles.
