A Because whenever you’re adding integers that have the same thing you keep the same signs in at the absolute value of each number

B because if you have something like 2+-3 it would equal -1 because 3-2 is 1 and -3 is the larger number

Angle 5 and 6 are supplements and angle 5 is 24 more than half the measure of angle 6. find the measure of each angle.

brilliants [131]

Supplementary angles equal 10 degrees.

Let angle 6 = X

Angle 5 is 24 more than half of angle 6, which can be written as 1/2X +24

So now we have X + 1/2x +24 = 180

Combine the like terms ( X +1/2X = 1.5X)

1.5x + 24 = 180

Subtract 24 from each side:

1.5x = 156

Divide both sides by 1.5:

x = 156 / 1.5

X = 104

Angle 6 = 104 degrees.

Angle 5 = 180 - 104 = 76 degrees

12=5x-13x-44. answer it in multi-step equations

fomenos

12=5x-13x-44

combine like terms

12 = -8x -44

add 44 to each side

12+44 = -8x

56= -8x

divide by -8 on each side

56/-8 = x

-7 =x

The vertical of three squares are joined to form a right triangle , what is the area of the largest square

lakkis [162]

Answer:

43cm²

Step-by-step explanation:

let's first consider the area of a square.

the area is L² which means all sides are equal so we take the length times the breadth which is both equal because like we said all sides are equal.

so to find the side of the square using the area, we take the square root of both of the area.

$\sqrt{25} = 5$

and also

$\sqrt{18} = 4.2$

so we have the height of the triangle as 5cm and the base is 4.2cm.

now, from the triangle, since we have two sides and it's a right-angled, we can use Pythagoras' formula.

$\sqrt{ {5}^{2} + {4.2}^{2} } = 6.53cm$

so the side 6.53cm is also the same side as the largest triangle. Since it's a square, all sides are equal. So we find the area of the largest triangle by using the formula

Area = L²

Area = 6.53²

Area = 42.6cm

the nearest cm square

Area = 43cm²

A box contains 1079 counters which are coloured either black, white or red.

aleksley [76]

<u><em>The total number of red counters that are in the box is; 728 red counters</em></u>

We are told that the box contains 1079 counters.

Let the number of white counters be x.

Let the number of red counters be y.

Let the number of black counters be z.

Thus;

z:x = 2:7

Thus; 2x/7 = z

Also, we are given;

x:y = 3:8

Thus;

8x/3 = y

Since total number in the box is 1079,then;

x + y + z = 1079

x + (8x/3) + (2x/7) = 1079

Multiply through by 21 to get;

21x + 56x + 6x = 22659

83x = 22659

x = 22659/83

x = 273

2x/7 = z

Thus; z = 2 × 273/7

z = 78

8x/3 = y

y = 8 × 273/3

y = 728

Thus,there are;

273 white counters

728 red counters

78 black counters.
