Answer:

706.25

Step-by-step explanation:

well i be smart my friend XD

1 + 1 (13 - 1 * 15) + 123 (23 / 4)

1 + 1 * - 2 + 123 x 5.75

1 - 2 + 707.25

-1 + 707.25

706.25

Answer:

Step-by-step explanation:

1 × 1(13 - 1 × 15) + 123 × (23/4) = 1 × 1(13 - 15) + 123 × (23/4)

= 1 × 1(-2) + 123 × (23/4)

= 1 × (-2) + 123 × (23/4)

= 1 × (-2) + 123 × (5.75)

= -2 + 123 × (5.75)

= -2 + 707.25

= 705.25

Answer: 12 and -4

Step-by-step explanation:

Assume the larger number is x and the smaller one is y.

In that case the relevant simultaneous equations are:

x + y = 8

2x + 4y = 8

Use substitution to find relative value of y:

x + y = 8

y = 8 - x

Use to solve equation:

2x + 4y = 8

2x + 4(8 - x) = 8

2x + 32 - 4x = 8

2x  - 4x= 8 - 32

-2x = -24

x = -24 / -2

x = 12

y = 8 - x

= 8 - 12

= -4

The slope of a line perpendicular to x+y=5 is 1

The value of x in the triangle shown is 68.

A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.

We are Given triangle is an isoceles 56=56

Thus, the sum of angles of triangle is 180.

X+56+56=180

X=180-112

X=68

Therefore, the value is X is 68.

Step-by-step explanation:

The origional question is ¨A turtle travels 1/2 mile in 1/9 hour. At this rate, how far can the turtle travel in an hour¨ To be honest i have no clue how to explain it but that is the awanser.

The turtle will travel  [tex]4\frac{1}{2}[/tex] in an hour.

A proportion is an equation in which two ratios are set equal to each other.

Given that, a turtle travels 1/2 mile in 1/9 hour. we need to find, at this rate, how far can the turtle travel in an hour.

We will solve this by using proportionality, since, rate is constant,

Let the turtle travels x miles in an hour,

Therefore,

x / 1 = (1/2) / (1/9)

x = 1/2 × 9

x = 9/2

x = [tex]4\frac{1}{2}[/tex]

Hence, the turtle will travel  [tex]4\frac{1}{2}[/tex] in an hour.

The size of the angle 'x' is 117°

An external angle of a triangle is an angle formed by extending one side of the triangle and intersecting with the extension of another side.

In a triangle, the measure of an external angle is equal to the sum of the measures of the two opposite interior angles.

Here we have  a triangle

Let the ABC be the triangle as given in the picture

=> ∠A = 38°  

From the baseline BC

=> Measure of B = 180° - 101° = 79°

As we know

In a triangle, the measure of an external angle is equal to the sum of the two opposite interior angles

=> x = ∠A + ∠C

=> x = 38° + 79°

=> x = 117°  

Therefore,

The size of the angle 'x' is 117°

Answer:

112 minutes

Step-by-step explanation:

Suzanne can put up 20 feet of fencing in 64 minutes.

We need to find minutes it will take to put up 35 feet of fencing.

20 feet = 64 minutes

1 feet = (64/20) minutes

For 35 feet,
