Answer: 1
Step-by-step explanation: You are starting with (a, b)
(a, -5) means that when b is -5, a is a
So substitute-5 into the equation for b and solve for a
3a = -2b - 7
3a = -2(-5) - 7
3a = 10 - 7
3a = 3
a = 1
Answer:
Ryan attempted 90 shots
Step-by-step explanation:
63 is 70% of 90
90 x .7 = 63
Problem 1
<h3>Answer: 37.33 </h3>
------------------
Work Shown:
1 liter = 1000 mL
0.56 liters = 560 mL (multiply both sides by 0.56)
x = number of tablespoons needed to fill water bottle
1 tablespoon = 15 mL
x tablespoons = 15x mL (multiply both sides by x)
Set 15x and 560 equal to each other. Solve for x
15x = 560
x = 560/15
x = 37.333
x = 37.33
=================================================
Problem 2
<h3>Answer: 545</h3>
------------------
Work Shown:
From the previous problem, a 0.56 L water bottle has 560 mL of water.
Subtract off 15 mL to get
560 - 15 = 545
A filled water bottle has 545 more mL of water compared to a tablespoon of water.
Answer:
b + d = 180°, a = d and a = c
Step-by-step explanation:
With the figure we can see that the only way for them to be parallel is that the angles are similar with their counterpart, for example that a = d. a = c will show that all angles are equal in order to be m and n parallel. Finally b + d = 180° shows that the only way for this to be true is that m and n are parallel.
