Answer:
120:300 is in the same ratio as 2:5. Can you add the pound sign? My keyboard does not have it.
Step-by-step explanation:
Add the two parts of the ratio together
2 + 5 = 7
Find 5:7
5:7 = x:420
5/7 = x/420 Cross multiply
7x = 5 * 420 Combine the right
7x = 2100 Divide by 7
x = 2100/7
x = 300
Find the second number
420 - 300 = 120
120 : 300 is the answer
Divide top and bottom by 60
120/60 = 2
300 / 60 = 5
Answer:
So W is going to stand for width and L is going to stand for length.
L= 2W+6
78=2L + 2W
Those are the two equations you will use. So plug in L=2W+6 into the other one and solve.
78= 4W+12 +2W
(simplify)
78=6W+12
(-12 from both sides)
66=6W
(divide by 11)
W=11
Replug W into your equation to find L.
L=22+6
(simplify)
L=28
I hope this is right

Step-by-step explanation:
<u>Answer plus step-to-step explanation:</u>
1. Slope formula = Change in y ÷ change in x.
i.e slope(m) = (Δ means change in)
2. Slope-intercept form is representing equation of a straight line on cartesian plane in the form y = mx + c. <em>Where (m) is the slope of that line and c is the y-intercept.</em>
3. Standard form - is writing numbers in the form of number times ten to power of an exponent. This is also referred to as scientific notation form.
<u>Example:</u>
To write 512 in standard form would be 5.12 × 10²
