Find the value of x<br> m<2=4x+12

Sergeu [11.5K]

Answer:

x = 1

Step-by-step explanation:

the angle 2 is equal to 52, because triangles add up to be 180, and 180 - 76 and divided by two is 52. 52 = 4x + 12. Divide both sides by four, then subtract 12. x = 1

5 sweets cost 30p altogether, how much do 7 sweets cost?

Nezavi [6.7K]

The best way to find out what 7 sweets cost, firstly, you should find out what one sweet would cost. You have 5 sweets, with a total cost of 30p. You should divide 30 by 5, giving you 6p per sweet. To get the cost of 7 sweets, you have to multiply 6p by 7, giving you 42p. Therefore, the cost of 7 sweets is 42p. Hope this helps :)

What’s the vertical and horizontal line?

coldgirl [10]

Answer:

Part 1) Vertical line : $x=1$

Part 2) Horizontal line : $y=-4$

Step-by-step explanation:

Part 1) Write the equation for the vertical line passing through the point (1,-4)

we know that

The equation of a vertical line (parallel to the y-axis) is equal to the x-coordinate of the point that passes through it

The x-coordinate is 1

therefore

The equation of the line is

$x=1$

Part 2) Write the equation for the horizontal line passing through the point (1,-4)

we know that

The equation of a horizontal line (parallel to the x-axis) is equal to the y-coordinate of the point that passes through it

The y-coordinate is -4

therefore

The equation of the line is

$y=-4$

A furniture store has a sale during which the sale price of a sofa is 1/3 off its original price. The original price

dmitriy555 [2]

Answer:

$694.06

Step-by-step explanation:

OG price= 1,029

discount=.05

sales tax =.065

1/3(og price)=1/3(1029)=343

one third of $1,029 is 343, hence we take off $343 from the orginial price

1029-343= $686--> sales price

.05*salesprice= .05*686=34.3

subtract 5% discount: 686-34.3= $651.71

=find 6.5% tax: .065*651.71= $42.36

add 6.5% tax: 651.81+42.36=694.06
