Answer:
120x138 in or 11.5x10 feet
Step-by-step explanation:
Step 1:
convert the feet to inches
10(feet)*12(inches)=120 inches
Step 2:
120(width)+18(length)=138 inches
Step 3:
width: 120 in OR 10 feet
length: 138 inches OR 11.5 feet (when divided by 12)
Hope this helps!
Answer:
7:5 is the same as 21: 15
Step-by-step explanation:
21/7 = 3 and 3*5=15
i divided 21 by 7 to see how many times it was multiplied to get there, so i could do the same thing to the 5
I hope this helps :)
Answer:
(- 4, 27 )
Step-by-step explanation:
Equate the right sides of both equations, that is
x² - 2x + 3 = - 2x + 19 ← subtract - 2x + 19 from both sides
x² - 16 = 0 ← in standard form
(x - 4)(x + 4) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 4 = 0 ⇒ x = - 4
Substitute these values into f(x) = - 2x + 19
f(4) = - 2(4) + 19 = - 8 + 19 = 11 ⇒ (4, 11 )
f(- 4) = - 2(- 4) + 19 = 8 + 19 = 27 ⇒ (- 4, 27 )
the real square root of 0.0009 is 0.03
Answer:
The Equation is
4x+2y= 200
Then total number of candy bars is
X+Y
Step-by-step explanation:
Shelby made $200 from selling x at $4 each and y at $2 each.
Let's have in mind that x is the number of large candy bars
And y is the number of small candy bars
The equation is simple
The amount it was sold is going to be the coefficient of the numbers we don't Know...
So
Equation is
4x+2y= 200
Then total number of candy bars is
X+Y
