Abdul's gas tank is 1/5 full. After he buys 7 gallons of gas, it is 7/10 full. How many gallons can Abdul's tank hold?

eduard

Answer: 14 gallons

Step-by-step explanation:

Let's call the total gallons of gas Abdul's tank can hold <em>x</em>.

Then, based on the information given in the problem, you can write the following expression:

$\frac{1}{5}x+7=\frac{7}{10}x$

Therefore, when you solve for x, you obtain the following result:

$\frac{1}{5}x+7=\frac{7}{10}x\\\\\frac{1}{5}x-\frac{7}{10}x=-7\\\\-\frac{1}{2}x=-7\\\\-x=(-7)(2)\\x=14$

Joyce paid $140 for an item at the store that was 20 percent of the original price. What was the original price?

Vesna [10]

Answer:

$175

Step-by-step explanation:

Equation for Price Reduction:

Original Price * Percent Remaining of Original = New Price

Plug in the given values into the equation:

Original Price * 0.8 = $140

Divide both sides by 0.8 to isolate the Original Price:

140/0.8 = 175

Help me on calculating the area of the shaded part

Ymorist [56]

Answer:

$1051 .55 {mm}^{2}$

Step-by-step explanation:

Find the area of the square - area of 4 sectors

We'll use the formula to find one sector area

$a = \frac{1}{2} \times {r}^{2} \times x$

where r is the radius of one sector and x is the angle in radians

Since each angle is in a square, the angle of the sectors is 90 degrees.

Convert degrees to radians

$90 = \frac{1}{2} \pi \: rad$

The radius of one sector is given by 70mm/2=35mm

One sector area:

$\frac{1}{2} \times {35}^{2} \times \frac{1}{2} \pi = 306.25\pi$

Area of all 4 sectors:

$4 \times 306.25\pi = 1225\pi$

Area of the square:

$70 \times 70 = 4900$

Hence, Area of square - 4 Sectors:

$4900 - 1225\pi = 1051.55 {mm}^{2} (2dp)$

I will mark you brainiest if you can answer this <br> 12 - 13 x ≥38

Shtirlitz [24]

<h3><u>Explanation</u></h3>

Given Inequality

$12 - 13x \geqslant 38$

Solve the Inequality for x-term by making x as the subject.

Solving Inequality is almost the same as solving the equation.

$- 13x \geqslant 38 - 12 \\ - 13x \geqslant 26$

The problem is here. Some people might forget that when we move the negative coefficient to another side, we have to flip/swap or change the sign to opposite. That means we have to change from >= to <=

$x \leqslant \frac{26}{ - 13} \\ x \leqslant - 2$

Answer Check by substituting x = -2 in the Inequality.

$12 - 13( - 2) \geqslant 38 \\ 12 + 26 \geqslant 38 \\ 38 \geqslant 38$

The Inequality is true for x = -2 and that means it is also true when x is lesser than - 2.

Substitute x = -3

$12 - 13( - 3) \geqslant 38 \\ 12 + 39 \geqslant 38 \\ 51 \geqslant 38$

Notice that if we substitute the number that are lesser or equal to -2, the Inequality will be true.

<h3><u>Answer</u></h3>

<u> $\large \boxed{x \leqslant - 2}$ </u>
