Answer:
D
Step-by-step explanation:
Integers: a WHOLE number that can be positive, negative or zero
-22 is a negative whole number
Rational number: Any number that can be written as a fraction with integers.
-22/1 can be the fraction
1 is 4 and 4 and 4 is 11 and 5 is 15
X=-1 and y=3
To solve this, because y is equal to 2x+5, you can substitute 2x+5 into the bottom equation for y.
You now have 3x - (2x + 5) =-6
This can be solved like a normal equation. Multiply each term in the parenthesis by -1.
3x - 2x - 5 = -6
Subtract 2x from 3x
x - 5 = -6
Add 5 to both sides
x=-1
Now you can solve for y by plugging -1 in for x in either equation. Im going to use the top one.
y= 2(-1)+5
y= -2+5
y=3
You can check your answer by plugging in the values for x and y into both equations and making sure both sides equal each other.
Answer:
19 cm³
Step-by-step explanation:
The figure cam be decomposed into two cuboid.
✔️Dimension of cuboid 1:
L = 2 cm
W = 1 cm
H = 8 - 3 = 5 cm
Volume = L * W * H
Volume = 2*1*5 = 10 cm³
✔️Dimension of cuboid 2:
L = 3 cm
W = 1 cm
H = 3 cm
Volume = L*W*H = 3*1*3
Volume = 9 cm³
✅Volume of the irregular figure = 10 + 9 = 19 cm³
