Answer:
6x-76
Step-by-step explanation:
If you graph it out, you'll realize it makes a line that cuts the y-intercept at -76, thus the last value. The slope also has a gradient of 6, thus the coeffecient of x.
Answer:
2 pairs
Step-by-step explanation:
If we convert 3 3/5 into an informal fraction, it would be 18/5 (3*5+3 for the numerator) and 1 4/5 would be 9/5 (1*5+4 for the numerator). 18/5 divided by 9/5 is the same as 18/5 * 5/9 (the reciprocal of 9/5) which equals 2. Therefore she can make 2 pairs of pants.
Answer:
The testing statistic is -2.237
Step-by-step explanation:
Test statistic (z) = (sample mean - population mean) ÷ (population standard deviation/√n)
sample mean = 6.3 ounces
population mean = 6.4 ounces
population standard deviation = 0.2 ounces
n (sample size) = 20
z = (6.3 - 6.4) ÷ (0.2/√20) = -0.1 ÷ 0.0447 = -2.237
Answer:
1. 5
2. 4
3. 20
4. 10
Step-by-step explanation:
You count the units of the length and width of the triangle which is also the same for the rectangle and l*w=the area (length is the longer side).
Halve the area of the rectangle to find the area of the triangle.
Answer:
B. (-2,3)
Step-by-step explanation:
-3x+5y = 21
x=2y-8
Substitution
-3(2y-8)+5y =21
-6y+24+5y=21
-y+24=21
-y=-3
y=3
Plug-in other equation
2*3-8=x
6-8=x
x=-2
