Answer:
You need to get a 95 on the next test to have a 90 grade average.
Step-by-step explanation:
(85 + 90 + n)/3 = 90
<u>Step 1: Multiply both sides by 3</u>
(85 + 90 + n)/3 * 3 = 90 * 3
85 + 90 + n = 270
<u>Step 2: Subtract 85 from both sides</u>
85 + 90 + n - 85 = 270 - 85
90 + n - 90 = 185 - 90
n = 95

Letter b. (2,5) is the only one that when plugged into the inequality above still makes the inequality true because 7<=7 and 5>2
Answer:
113
Step-by-step explanation:
Your first point should always be shown in the y-intercept following the standard form for slope-intercept form
Y = mx + b
b = y - intercept
In this case your first point would be (0,1)
You next point would be following the slope which is -2x. When you graph a equation always know that it is rise over run. For this line, it would be going from left to right since it is a negative line.
Your second point would go down 2 points from your starting point (0,1) and run 1 to the right in the x-axis, which is also called, (1,-3)
Answer:
g=3 yards
Step-by-step explanation:
Since the 3yd on the big triangle is reduced to 1 yd on the small triangle divide 9 by 3 to get the missing side length of 3 yards. Hope this helps :)
