If every fourth customer gets stickers and every tenth customer gets a notebook, which customer will get both?

1 answer:

6 0

The 20th costumer will get both.
You have to fine the least common multiple of both numbers. So the closest those two numbers have is 20.
$4 \times 5 = 20 \\ 10 \times 2 = 20$

A system of equations is graphed on a coordinate plane.

zavuch27 [327]

Answer:

Option C is correct.

(1, 4)

Step-by-step explanation:

A system of equation is given :

2x + 3y =12 .....[1]

4x + 2y =10 .....[2]

Multiply equation [1] by 2 both sides we get;

$2(2x+3y) = 2(12)$

Using distributive property i,e $a \cdot(b+c) = a\cdot b+ a\cdot c$

4x + 6y = 24 .....[3]

Subtract equation [2] from [3] to eliminate x we get;

4x + 6y - 4x - 2y= 24 - 10

Combine like terms;

4y = 14

Divide both sides by 4 we get;

y = 3.5

Substitute the value of y in equation [1] we have;

2x + 3(3.5) =12

2x + 10.5 = 12

2x = 12 -10.5

2x = 1.5

Divide both sides by 2 we get;

x = 0.75

Solution = (0.75 , 3.5)

Best estimate solution = (1, 4)

Therefore, the best estimate solution of the given system of equation is, (1, 4)

4. If DF = 9x - 39, find EF. Help I’m so confused!!!!

topjm [15]

Answer:

EF =58

Step-by-step explanation:

from the illustration,

EF =DF - DE

given that DF =9x-39 , DE =47 EF=3x +10

substitute them into the formula,

3x +10=9x-39 - 47

solving for x

3x +10 =9x -86

grouping like terms

3x - 9x =-86 -10

-6x=-96

dividing through by -6

 $\frac{ - 6x}{ - 6} = \frac{ - 96}{ - 6}$ 

 $x = \frac{96}{6}$ 

 $x = 16$ 

but EF=3x+10

substitute x=16 into it to get the EF

EF= 3(16)+10

EF=48+10

EF=58

How to borrow if you can't subtract from the lowest number on top

Elis [28]

Go to the number next to the one you cannot subtract from, take one away, and add a one in front of the number you cannot subtract from. e.g.
27 1(1)7 the answer would be 9
-8 -8

for your problem the answer would be 1109
