Given the system of equations:

To solve it by substitution, follow the steps below.
Step 1: Solve one linear equation for x in terms of y.
Let's choose the second equation. To solve it for x, add 3y to each side of the equations.

Step 2: Substitute the expression found for x in the first equation.

Step 3: Isolate y in the equation found in step 2.
To do it, first, add 48 to both sides.

Then, divide both sides by 15.

Step 4: Substitute y by 5 in the relation found in step 1 to find x.

Answer:
x = -9
y = 5
or (-9, 5)
Also, you can graph the lines by choosing two points from each equation, according to the picture below.

Answer:
This lesson combines the Draw Loop that students first saw in Lesson 7 and the Counter Pattern that they learned in Lesson 8 to create programs with purposeful motion. By either incrementing or decrementing sprite properties, such as sprite.x, you can write programs that move sprites in expected patterns, instead of the randomization that we used in the past. The animations that students learn to create in this lesson lay the foundation for all of the animations and games that they will make throughout the rest of the unit.

Answer:</h2>
Total decease will be 0.75 cm
<h2>
Step-by-step explanation:</h2>
Decrease in height in each year = 1/4 cm
The decrease in 3 years would be
3 time 1/4
So the total decrease in three years will be
0.75
Answer:
3500
Step-by-step explanation:
70% = 70/100 70*0.25=17.5
17.5*2=35 35=200 35.00 *100= 3500.
