Answer:

x = -10

Step-by-step explanation:

Simplify both sides of the equation.

2 (x+3) = x − 4

(2) (x) + (2) (3) = x + −4 (Distribute)

2x + 6 = x + − 4

2x + 6 = x − 4

Subtract x (1x) from both sides

2x + 6 − x = x − 4 − x

x + 6 = − 4

Subtract 6 from both sides

x + 6 − 6 = − 4 − 6

x = -10

Answer:

x = -10

Step-by-step explanation:

2(x+3) = x-4 --> multiply (x+2) times 2

2x+6 = x - 4 --> subtract x from both sides

x+6 = -4 --> subtract 6 from both sides

x = -10

Lori creates the following design for a T-shirt.

Solution-

From the figure,

AE = 2.4

EB = 2.8

BC = 11.7

Area of rectangle 1 = 8.68 sq.in

$\Rightarrow FH \times HI=8.68$

$\Rightarrow EB \times HI=8.68$ (∵ sides of the rectangle 2)

$\Rightarrow 2.8 \times HI=8.68$

$\Rightarrow HI=3.1$

Area of Triangle 1 = 6.48 sq.in

$\Rightarrow \frac{1}{2}\times AE \times EG= 6.48$

$\Rightarrow \frac{1}{2}\times AE \times (EF+FG)= 6.48$

$\Rightarrow \frac{1}{2}\times AE \times (EF+HI)= 6.48$ (∵ sides of the rectangle 1)

$\Rightarrow EF+3.1= 5.4$

$\Rightarrow EF=2.3$

$\Rightarrow BH=2.3$ (∵ sides of the rectangle 2)

$BC = BH+HI+IC$

$\Rightarrow 11.7= 2.3+3.1+IC$

$\Rightarrow IC=6.3$

The area of Rectangle 2,

$=EB\times BH =2.8\times 2.3=6.44\ sq.in$

The area of Triangle 2,

$\frac{1}{2}\times GI \times IC=\frac{1}{2}\times EB \times IC=\frac{1}{2}\times 2.8 \times 6.3=8.82\ sq.in$

The area of the whole figure = Area of Triangle 1 + Area of rectangle 1 + Area of Triangle 2 + Area of rectangle 2

= 6.48+8.68+8.82+6.44=30.42 sq.in

Stefan purchases materials to make dog collars. Stefan purchases 10 buckles in a pack and 12 straps in a pack. Stefan doesn't wa

CaHeK987 [17]

Answer:

Step-by-step explanation:

Assuming it take 1 buckle and 1 strap per collar, that means we just need to find the lowest common multiple of these 10-pack buckles and 12-pack straps.

For 10: 0, 10, 20, 30, 40, 50, "60", 70, 80, 90, 100...

For 12: 0, 12, 24, 36, 48, "60", 72, 84, 96, 108, 120...

From this, it is obvious that 60 is the lowest common multiple of these two numbers. Therefore, we know that Stefan can make dog collars without having leftover supplies by using 6 10-pack buckles and 5 12-pack straps.

From this, we know that Stefan does not need to buy 120 of either the buckles or the straps.

Answer for Brainliest 1)7/4+5/8= 2)3/2+4/3= 3)2/3+10/7= 4)4-3/17

Sunny_sXe [5.5K]

Answer:

See below.

Step-by-step explanation:

1) 7/4 + 5/8

= 14/8 + 5/8

= 19/8 or 2 3/8

2) 3/2 + 4/3

= 9/6 + 8/6

= 15/6

= 5/2 or 2 1/2

3) 2/3 + 10/7

= 14/21 + 30/21

= 44/21 or 2 2/21

4) 4 - 3/17

= 68/17 - 3/17

= 65/17 or 3 14/17
