Answer:
Jacinth = 17
Naomi = 13
Step-by-step explanation:
they add up to 30 and follow the criteria
Answer: x=-46
Step-by-step explanation:
Assuming the expression equals 0 (I'm not sure since you didn't explicitly state that, but I inferred for the sake of answering the question):
4(-8x+5)-(-33x-26)=0
-32x+20+33x+26=0
1x+46=0
x=-46
Hope that helps!
28 men are needed to paint the room in 3 hours
<h3><u>Solution:</u></h3>
Given that it takes 12 hours for 7 men to paint a room
We are asked to find number of men required to paint the room in 3 hours
Recognize, "paint the room" is 1 task. One job.
7 men -------- 12 hours ------ 1 job
(7/7) = 1 men ------- 12 x 7 (84) ------- same 1 job
The one men is rate is 84 hours to do the job
We can express this as 1/84 jobs per hour, the one-person rate
Now lets find how many men needed to paint the room in 3 hours
Let the required number of men for 3 hours be "a"
The rates of each person is simply additive.
corresponds to rate x hours = jobs and "a" is a variable for how many men
Thus 28 men are needed to paint the room in 3 hours
Answer:
Slope=6
Explanation:
Given a line that passes through the point (0,-4) and (1, 2), we are required to find the slope.
Whenever we are given two points on a line, we can find the slope of such a line by using the formula below:
First, label the points.
Substitute the values into the formula.
The slope of the line is 6.
a is SSS, c is SAS and d is ASA, all good congruent triangle theorems.
b is AAA, good to show similar triangles, not necessarily congruent triangles.
Answer: b
