To solve by substitution, you need to fill in the value for either x or y. Since y = x + 5, you already have the y value. It's x + 5. Now you need to find x before you can go any further. So let's take 5x + y = 3 and fill x + 5 in for y.
5x + y = 5
5x + x + 5 = 3
Now solve for x.
5x + x + 5 = 3
6x + 5 = 3
6x = 3 - 5
6x = -2
x = -2/6 or -0.33
Now solve x + 5 for y.
y = x + 5
y = -0.33 + 5
y = 4.67
So x = -0.33 and y = 4.67
1 km = 1000m
so 36 km= 36 000 m
ANSW: are equal
Answer:
SSS Theorem
Step-by-step explanation:
All the corresponding sides of these two triangles are of equal length, proving their congruency. Although it can be assumed that they also share the same angles, no angle information is directly given to prove the fact.
Answer:
25.9%
Step-by-step explanation:
100000÷13500×100
Subtract the 74.074 because 100000 is 74.074 of 135000
We are told in the question that 1 carat is equal to 200 mg.
The Hope Diamond is 44.5 carats. Let's multiply the weight of 1 carat by 44.5 to get the weight of the Hope Diamond in mg:

The total weight of the Hope Diamond is 8,900 mg. However the question asks for the weight in grams. There are 1000 mg in 1 gram, so let's divide the known weight of the Hope Diamond in mg by 1000 to get the weight converted to grams:

Now we know that
the weight of the Hope Diamond is equal to 8.9 grams.
