<u>Estimate
5.</u> 49.2 this is actually 20% but its close enough to estimate <u>
6.</u> 120 this is closer to 150%<u>
7.</u> 226.8 this is 70%
<u>
8.</u> 36 this is closer to 55%
<u>
9.</u> It would be closer to fifteen minutes because 25% = 1/4 and 15/45 = 25% and 45 minutes is close to 50 min
<u>write an equation
</u><u>10.</u> 14% = .14 so .14×64 = 8.96<u>
</u><u>
11.</u> x = .36 × 194 x = 69.84<u>
12.</u> .82x = 73.8 divide each side by .82 x = 90<u>
13.</u> 75 = 50x divide each side by 50 x = 1.50 or 150%
The sum of complementary angles is 90 degrees, thus
3x + 6 + 3x + 18 = 90
=> 6x + 24 = 90
=> 6x = 90 - 24 = 66
=> x = 66 / 6 = 11
=> m<A = 3(11) + 6 = 33 + 6 = 39 degrees.
Answer:
y = -2x + 9
Step-by-step explanation:
The general shape of the equation is y = ax + b, you just have to find a and b.
b is simple, it is the y coordinate where the line crosses the y axis, i.e., b=9.
a is the slope of the line. This is the change in y when you take one step to the right. The change is -2.
Hence y = -2x + 9
This is an example of how you solve an inequality.
Rectangles have four right angles
thus ∡ R + ∡S = 90° + 90°
= 180°
