Answer:
The dimensions of the herb garden on the scale drawing are 2.4 by 6 inches
Step 1 (finding the scale factor):
12/10 (inches/feet) or 1.2 (inches/feet)
(1.2 inches<em> </em>in the <em>drawing</em> represent 1 foot in real life)
Step 2 (finding the dimensions of the herb garden on the scale drawing):
Real life dimensions are 2ft by 5ft so we multiply by the <em>scale factor</em>:
2ft = 2 x 1.2 = 2.4 inches
5ft = 5 x 1.2 = 6 inches
So the dimensions of the herb garden on the scale drawing are 2.4 by 6 inches.
Answer:
He has driven 16 miles so far
Step-by-step explanation:
The unknown in your equation is the total length of Trey's drive, which we will call "x".
From the problem statement, you know that 12 is three-fourths of x so set up the following equation and solve for "x":
3/4(x) = 12
multiply both sides of the equation by 4/3 to isolate "x":
(4/3)(3/4)(x) = (12)(4/3)
therefore
x = (12)(4)/(3) = 16
Answer: D
Step-by-step explanation:
Consider the first equation. Subtract 3x from both sides.
y−3x=−2
Consider the second equation. Subtract x from both sides.
y−2−x=0
Add 2 to both sides. Anything plus zero gives itself.
y−x=2
To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.
y−3x=−2,y−x=2
Choose one of the equations and solve it for y by isolating y on the left hand side of the equal sign.
y−3x=−2
Add 3x to both sides of the equation.
y=3x−2
Substitute 3x−2 for y in the other equation, y−x=2.
3x−2−x=2
Add 3x to −x.
2x−2=2
Add 2 to both sides of the equation.
2x=4
Divide both sides by 2.
x=2
Substitute 2 for x in y=3x−2. Because the resulting equation contains only one variable, you can solve for y directly.
y=3×2−2
Multiply 3 times 2.
y=6−2
Add −2 to 6.
y=4
The system is now solved.
y=4,x=2
