What is 6x+7y=4x+4y6x+7y=4x+4y

Mathematics
1 answer:
eimsori [14]3 years ago
6 0

we have

6x+7y=4x+4y

we figure out that

the solution is ----> (x,-4)

substitute the value of y=-4 in the equation

6x+7*(-4)=4x+4*(-4)

6x-28=4x-16

Combine like terms

6x-4x=28-16

2x=12

x=12/2

x=6

So the the missing value is x=6.

PLEASEE HELPPP!!!
Harlamova29_29 [7]

Answer:

The amount is $649.46 and the interest is $49.46.

Step-by-step explanation:

STEP 1: To find amount we use formula:

A=P(1+rn)n⋅t

A = total amount  

P = principal or amount of money deposited,

r = annual interest rate  

n = number of times compounded per year

t = time in years

In this example we have

P=$600 , r=8% , n=4 and t=1 years

After plugging the given information we have

AAAA=600(1+0.084)4⋅1=600⋅1.024=600⋅1.082432=649.46

STEP 2: To find interest we use formula A=P+I, since A=649.46 and P = 600 we have:

A649.46II=P+I=600+I=649.46−600=49.46

Billy Jean is buying fabric. For the same material, Sew Right charges $4.00 per yard and an initial $5.00 convenience fee. Stitc
topjm [15]
For this problem, there are two situations. To solve this, let's construct an algebraic equation for each. Let's find the total cost. Let x be the number of yards.

Situation 1: Cost = 4x + 5
Situation 2: Cost = 6x +2

Now, both situations have the same cost. So,

4x + 5 = 6x + 2
6x - 4x = 5 - 2
2x = 3
<em>x = 3/2 or 1.5 yards</em>
