After 10 weeks, the boys will have same amount in savings.
Step-by-step explanation:
Given,
Roberto already have $30.
Amount saved each week = $5
Let,
x be the number of weeks.
R(x) = 30+5x
Amount saved by Jack each week = $8
J(x) = 8x
For same amount, the functions will be equal.
R(x) = J(x)

Dividing both sides by 3

After 10 weeks, the boys will have same amount in savings.

Equation: y = 6 - 2x
Fill in the x numbers in the x which is next to -2 —> y = 6 - 2(0), y = 6 -2(1), y = 6 -2(3), and etc.
A) 0 —> 6
1 —> 4
2 —> 2
3 —> 0
4 —> -2
5 —> -4
B) Put a dot on y axis on number 6, then go down by 2 because your subtracting 2
C) 6 - 2x = 3
-6 -6
-2x = -3
-2/-2 -3/-2
X = 1.5
Answer:
A.) JH = 1 in
B.) GH = 3/4 in
C.) m∠F = 62°
D.) m∠J = 118°
Step-by-step explanation:
In a parallelogram, opposite angles are congruent, adjacent angles are supplementary, and opposite sides are congruent.
A.) JH = FG = 1 in
B.) GH = FJ = 3/4 in
C.) m∠F = m∠H = 62°
D.) m∠J = m∠G = 180° -62° = 118°
The time that taken for the two trains is 1.2 hours.
The computation of the time taken for the two trains is shown below:
Given that
The westbound train travels 55 miles per hour.
And, the eastbound train travels 75 miles per hour.
So, the total speed is
= 55 miles per hour + 75 miles per hour
= 130 miles per hour
The distance is 156 miles
So, the time taken is

= 1.2 hours
Therefore we can conclude that the time that taken for the two trains is 1.2 hours.

A 30-60-90 triangle is special because of the relationship of its sides. Also <span>It turns out that in a 30-60-90 triangle, you can find the measure of any of the three sides, simply by knowing the measure of at least one side in the triangle.
Hope this helps. :)</span>
