Is 5/4 a solution to the problem: 3(+9)=4−7+7.

Alik [6]

Answer:

No the soultion is not equal to 1 1/4

The solution to the given question is either 6 3/4 or 4 /27

Step-by-step explanation:

Let

3(+9)=(4−7+7)x

27 = 4x

x= 27/4

x= 6 3/4 is the answer

Let

3(+9) x=(4−7+7)

27x = 4

x= 4/27

The plus sign inside the bracket indicates that 3 is multiplied with positive nine and -7 and +7 are cancelled and 4 is left behind.

If x is on the left side the answer will be 6 3/4 and if it is on the right side the answer is 4/27 .

In both cases the answer is not equal to 5/4 .

5/4 means 1 1/4 which is not equal to either 6 3/4 or 4/27

Find the measure of the arc TDB in the circle P shown below:

andrey2020 [161]

$\huge{ \mathfrak{ \underline{ Answer \: \: ✓ }}}$

The Angle formed by an arc on the centre of the circle is double the angle made by the same arc on the circumference of the circle.

So,

$\boxed{ \mathrm{ \angle TDB = \dfrac{1}{2} \angle TPB }}$

$\mathrm{\angle TDB = \dfrac{1}{2} \times 90 \degree}$

$\mathrm{\angle TDB =45 \degree }$

The cellular phone service for a business executive is $35 per month plus $0.40 per minute of phone use over 900 min. For amonth

Helen [10]

Answer:

1022 minutes

Step-by-step explanation:

Let x be the number of minutes the executive used the phone

There is a base charge of $35 and only minutes greater than 900 min are charged at the rate of $0.40 per minute

So total bill A = 35 + 0.4(x-900)

We know the bill was $83.80

So we can rewrite the equation as

35 + 0.4(x-900) = 83.30

and solve for x

To make it easier for computational purposes

1) Multiply both sides by 10

$35\cdot \:10+0.4\left(x-900\right)\cdot \:10=83.8\cdot \:10$

2) Perform individual multiplication

$350+4\left(x-900\right)=838$

3) Subtract 350 from both sides

$350+4\left(x-900\right)-350=838-350$

4) Simplify

$4\left(x-900\right)=488$

5) Divide both sides by 4

$\frac{4\left(x-900\right)}{4}=\frac{488}{4}$

6) Simplify

$x-900=122$

7) Add 900 to both sides to isolate x

$x-900+900=122+900$

8) Simplify to obtain x

$x=1022$

Answer: The executive used the phone for 1022 minutes that month

Point T is on line segment

Fofino [41]

Answer:

Numerical length of TU = 6

Step-by-step explanation:

A/q,

SU = ST+TU

5x = 4x-3 + 2x

5x = 4x+2x-3

5x = 6x -3

5x-6x = -3

-x = -3

x = 3

Verify:- Putting x = 3 in 5x =4x-3+2x

5(3) = 4(3)-3+2(3)

15 = 12-3+6

15= 9+6

15= 15

LHS =RHS Hence correct
