Kam is trying to find the solution to the system below. Her steps are below as well.
What did kam do wrong?
Answer:
Step 4
Step-by-step explanation:
In step 4, instead of adding 22 to both sides of the equation to combine like terms, Kam got rid of it completely. Starting from step 3, here is the correct way of solving it:
[tex]7x-22=18[/tex]
Add 22 to both sides
[tex]7x-22+22=18+22\\7x=40[/tex]
Divide both sides by 7 to isolate x
[tex]\frac{7x}{7}=\frac{40}{7} \\x=\frac{40}{7}[/tex]
I hope this helps!
Answer:
In step 4, she forgot to add 22 to 18
Step-by-step explanation:
In step 4, she forgot to add 22 to 18
It should've been:
7x = 40
x = 40/7
3 (40/7) + 2y = 18
120/7 + 2y = 18
2y = 18 - 120/7
2y = 6/7
y = 3/7

In ΔFGH, h = 9.6 inches, f = 2.5 inches and ∠G=78°. Find the length of g, to the nearest 10th of an inch.
Answer:9.4
Step-by-step explanation:
Answer: 9.4
Step-by-step explanation:
S.A.S.→Law of Cosines
a^2=b^2+c^2-2bc\cos A
g^2 = 9.6^2+2.5^2-2(9.6)(2.5)\cos 78
g^2 = 92.16+6.25-2(9.6)(2.5)(0.207912)
g^2 = 92.16+6.25-9.97976
g^2 = 88.43024
g=√88.43024 ≈9.404≈9.4

What is the product of -4 and 2 3/5
Answer:
6 3/

= 6.6
Step-by-step explanation:
Conversion a mixed number 2 3/
5
to a improper fraction: 2 3/5 = 2 3/
5
= 2 · 5 + 3/
5
= 10 + 3/
5
= 13/

To find new numerator:
a) Multiply the whole number 2 by the denominator 5. Whole number 2 equally 2 * 5/
5
= 10/
5
b) Add the answer from previous step 10 to the numerator 3. New numerator is 10 + 3 = 13
c) Write a previous answer (new numerator 13) over the denominator 5.
Two and three fifths is thirteen fifths
Add: 4 + 13/

5
= 20/
5

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(1, 5) = 5. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 1 × 5 = 5. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - four plus thirteen fifths = thirty-three fifths.
(System of equations) The difference of two numbers is 3. Their sum is 77. Find the numbers.
An ice cream factory makes 300 quarts of ice cream in 2 hours. How many quarts could be made in 12 hours? What was that rate per day?
Answer:
1800 in 12 hours
3600 in 24 hours
Step-by-step explanation:
300 in 2 hours
12/2 = 6 times as much in 12 hours
6(300) = 1800 in 12 hours
3600 in 24 hours

Answer:
converting 7.5miles to km.i have...
1mile = 1.6km
7.5miles=xkm...
cross multiplying I have..
xkm=7.5 × 1.6
xkm=12
Answer:
12km

5 miles = 8 km
→ Work out how much kilometres in a mile
1 miles = 1.6km
→ Multiply both sides by 7.5
7.5 miles = 12km

How many square units is the surface area of the box corresponding to the net?
Answer:
64
Step-by-step explanation:
We have two squares of 4x4 units and 4 rectangles of 4x2 units, therefore
[tex]2 \cdot (4 \cdot 4)= 2 \cdot 16 = 32 \text{ squre units}[/tex]
[tex]4 \cdot (4 \cdot 2)= 4 \cdot 8 = 32 \text{ squre units}[/tex]
Total Area is therefore 32 + 32 = 64 square units
Amber is on a family cell phone plan with the other 2 members of her family. The family gets 744 shared cell phone minutes a month, and each family member is limited to his or her equal share of the minutes. The only free calls are calls between family members. How many minutes per day can Amber talk on her cell phone with her friends during a 31-day month, without going over her share of the minutes?
Answer:
8 Minutes
Step-by-step explanation:
When dividing 744 by 3 family members you will get 248 minutes, but then dividing by 31 to tell the number for how long they can all be on per day you will get 8. 744 ÷ 3 ÷ 31 = 8.
