51t+9
product is multiplying, so 51 times t. Then 9 more than is +9, so it's 51t+9.
A = x + 5
B = x - 5
Top angle = 108 degrees
Answer:
4 ( 4 + 4 + 4 )
Step-by-step explanation:
Answer:
x: (6,0)
y: (0,-2)
Step-by-step explanation:
To find the x-intercept, substitute in 0 for y and solve for x
. To find the y intercept, substitute in 0 for x and solve for y
.
Ex -
X : 2x -6(0)=12
2x=12
2 cancels out with 2
12/2 = 6
Y: 2(0 )- 6y =12
-6y=12
negative 6 times negative 6 cancels
12/-6 = -2
Answer = 16 birds
1. Write out your equations
X = birds
Y= cats
x + y = 19
2.50x + 7.50y = 62.50
2. Isolate one variable.
x + y = 19
x = 19 - y
3. Plug this in as the variable in the other equation. Then, solve.
2.5(19 - y) + 7.5y = 62.5
47.5 - 2.5y + 7.5y = 62.5
-2.5y + 7.5y = 15
5y = 15
y = 3 (cats)
4. Solve for the other variable.
We know there were 19 animals in total on Monday. Since there were 3 cats, there must be 16 birds.
5. Double check by plugging the numbers into the original equations.
16 + 3 = 19
19 = 19 (true)
2.5(16) + 7.5(3) = 62.5
40 + 22.5 = 62.5
62.5 = 62.5 (true)
