Find the measure of the missing angle.

Answer:

a + 4b - 24

Step-by-step explanation:

simply multiply 4 to the numbers in the brackets. If there is an unknown variable then write it as it is. Don't forget the to multiply the signs as well.

4 x 1/4a = 1a = a

4 × b = 4b

4 × -6 = -24

Answer:

a + 4b - 24

Step-by-step explanation:

Expand brackets. Each term in the brackets is multiplied by 4.

4( 1/4a) + 4(b) + 4(-6)

4/4a + 4b - 24

Answer: x=26

Step-by-step explanation:

The element is remaining after 18 minutes with the rate of decaying of 26.8 % is 2.99 grams.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

An element with a mass of 820 grams decays by 26. 8% per minute.

Then the mass remaining after one minute will be

Remaining = 100 - 26.8

Remaining = 73.2 %

The element is remaining after 18 minutes will be

Mass = 820 × (0.732)¹⁸

Mass = 820 × 0.00364

Mass = 2.985

Mass ≈ 2.99

The element is remaining after 18 minutes is 2.99 grams.

Let X be the intersection of lines QR and NP.

By Power of a Point, we have [tex]QX\cdot XR=NX\cdot XP.[/tex]

(This can be proven with similar triangles by connecting QN and PR and using proportions with similar triangles [tex]\triangle QXN[/tex] and [tex]\triangle RXP[/tex].)

Plugging the values we know into [tex]QX\cdot XR=NX\cdot XP,[/tex] we have

[tex]12\cdot(x-2)=(3x-1)\cdot 3[/tex].

Dividing both sides by 3 gives

[tex]4(x-2)=3x-1.[/tex]

Distributing the left hand side gives

Subtracting 3x from both sides, we have

[tex]x-8=-1.[/tex]

Finally, adding 8 to both sides, we have

Simplify the following:

((2 + 3/4)×2)/5

Hint: | Express ((2 + 3/4)×2)/5 as a single fraction.

((2 + 3/4)×2)/5 = ((2 + 3/4)×2)/5:

((2 + 3/4)×2)/5

Hint: | Put the fractions in 2 + 3/4 over a common denominator.

Put 2 + 3/4 over the common denominator 4. 2 + 3/4 = (4×2)/4 + 3/4:

(((4×2)/4 + 3/4) 2)/5

Hint: | Multiply 4 and 2 together.

4×2 = 8:

((8/4 + 3/4)×2)/5

Hint: | Add the fractions over a common denominator to a single fraction.

8/4 + 3/4 = (8 + 3)/4:

Step-by-step explanation:

We are given the sequence or function:—

[tex]\displaystyle \large{a(n) = 3(2)^n}[/tex]

To find the sum of 1st term and 4th term, first we must find the first term and the fourth term which can be done by substituting n = 1 and n = 4.

[tex]\displaystyle \large{a(1)=3(2)^1}\\\displaystyle \large{a(1)=3 \cdot 2}\\\displaystyle \large{a(1)=6}[/tex]

Then when n = 4.

[tex]\displaystyle \large{a(4) = 3(2)^4}\\\displaystyle \large{a(4) = 3 \cdot 16}\\\displaystyle \large{a(4) = 48}[/tex]

Therefore, the sum of 1st term and 4th term is:—

Answer:

m = 6

Step-by-step explanation:

If the system of equations has no solutions, then the lines are parallel.

Parallel lines have the same slope.

The slope-intercept form of a linear equation is   y = mx + b
(where m is the slope and b is the y-intercept)

Therefore, the slope of the equation  y = 6x + 1  is 6

So the second equation should also have a slope of 6:  y = 6x + 3

Now compare both

Hence m=6

we can do this in 2 main ways.

1. using the fact that this is a metric system with 1m = 100cm.

15.24m + 2.98m = 18.22m = 18m 22cm

2. using fractions

15 24/100 m + 2 98/100 m =

Answer: x = 62.5 degrees

Step-by-step explanation:

Angle DEC is adjacent to the angle measuring 137 degrees, which means their sum is 180 degrees. Therefore:

Angle DEC + 137 = 180

We can subtract 137 from both sides:

Angle DEC = 43 degrees

We know that the sum of the angles in a triangle is 180 degrees, so we can set up an equation for triangle DEC.

We know Angle D + Angle C + Angle E = 180, so we can plug in the values given for each.

Therefore, x + 5 + x + 7 + 43 = 180

We can combine like terms:

2x + 55 = 180

Subtract 55 from both sides:

2x = 125

Divide both sides by 2:

x = 62.5 degrees
