Answer:
-4
Step-by-step explanation:
Two legs of the triangle are congruent as shown by the tick marks. This means that this is an isosceles triangle; in an isosceles triangle, the two base angles are also congruent. Which means <A and <B are congruent.
So to solve for x, set 28 and 10x+68 equal to each other.
28=10x+68
First, subtract 68 from both sides
-40=10x
Then, divide both sides by 10
-4=x
If you want to check your answer plug -4 back into the original equation.
28=10(-4)+68
28=-40+68
28=28, which is true, therefore -4 is correct.
<span>answer 1
Nancie is typing is represented by the equation
y = 35x
Therefore, the rate at which Nancie is typing is given by the slope of the straight line that in this case is:
35 words per minute
answer 2
To find the rate at which Suresh is typing we have to find the equation of the line with the data in the table.
For this case, the equation of the line will be given by:
y = 56x
Therefore, the rate at which Suresh is typing is given by the slope of the straight line which in this case is:
56 words per minute
answer 3
Nancie's rate = 35
Suresh's rate = 56
56-35 = 21 words per minute
Nancie's rate is 21words per minute less than Suresh's rate.

P = 2l + 2w
p-2w = 2l
p-2w/2 = l
Substitute the perimeter and you should be able to work it out

Answer:
6
Step-by-step explanation:
No. objects in one set = 7
Let there be n set
Then, No. objects in n set = 7*n = 7n
Given that total no of objects are 48
Thus,
7n = 48
n = 48/7 = (42+6)/7 = 42/7 + 6/7 = 6 + 6/7
n = 6 + 6/7
Thus, there will be 6 set which has 7 objects. fraction means one set is fraction 6/7 but set cannot be in fraction hence negating it.
Now, total objects in 6 sets = 6*7 = 42.
No. of objects left = 48 - 6 = 6
