Answer:

x = - 18

Step-by-step explanation:

Let certain number = x

The difference between half of a certain number and seven

x/2 - 7

is the same as

=

with adding two to that number

x + 2

Find the number

x/2 - 7 = x + 2

x - x/2 = - 7 - 2

( 2x - x ) / 2 = -9

2x - x = -18

x = - 18

Answer:

Step-by-step explanation:

Step 1. It should say that 9 squared + b squared equals 15 squared, where 15 should be c since it’s the hypotenuse.

Answer: x= 14

Step-by-step explanation: look at transversal ED. Angle E and angle D are alternate interior angles of this transversal. Alternate interior angles are equal. Now we need to find angle measure of D to solve. The triangle angle sum theorem states that all interior angles of a triangle sum to 180 degrees. 50+ 48 + D =180.

Measure of angle D is 82. Now that we have the two alternate interior angles, we set them equal to each other to solve.

6x-2= 82. Add 2 to both sides. 6x = 84. Divide both sides by 6. X =14

Step-by-step explanation:

1)

SA= 2 (Length x Breadth + breadth x height + Length x height)

SA= 2(2*5+5*6+6*2)=2(10+30+12)=104cm^2

2)

2(3*4+4*5+5*3)= 2(12+20+15)=94cm^2

3)

2(7*9+9*12+12*7)=2(63+108+84)= 510cm^2

4)

SA=

[tex]A=2πrh+2π {r}^{2}

[tex]A=2πrh+2π {r}^{2} [/tex]

= 2π 6*5+2π6*6= 188.495+226.194

SA= 414.689 cm^2

5)

2π7*4+2π*4*4=

SA=276.46 cm^2

6)

2π6*4+2π*4*4=

SA= 251.33 cm^2

7)

(3*4)/2=6

(3*4)/2=6

(3*8)=24

4*8=32

8*5=40

SA =6+6+24+32+40=108 cm^2

8)

(6*8)/2=24

(6*8)/2=24

6*12=72

8*12=96

10*12=120

SA= 24+24+72+96+120= 336 cm^2

9)

(5*12)/2=30

(5*12)/2=30

5*8=40

12*8=96

13*8=104

SA= 30+30+40+96+104= 300 cm^2

Answer:

p=19

Step-by-step explanation:

since the instructions say that ([tex]x^{13}[/tex])([tex]x^{6}[/tex]) is equivalent to [tex]x^{p}[/tex], we can make the equation:

([tex]x^{13}[/tex])([tex]x^{6}[/tex])=[tex]x^{p}[/tex]

now, apply the laws of exponents; [tex]a^{m} * a^{n} =a^{m+n}[/tex]

in that case, since we're multiplying x to the 13th power by x to the 6th, the result is [tex]x^{13+6}[/tex], which is [tex]x^{19}[/tex]

the equation now:

[tex]x^{19}[/tex]=[tex]x^{p}[/tex]

since the exponents are at the same base, we can solve the equation

19=p

so p is 19

hope this helps :)

Answer:

  x = 58

Step-by-step explanation:

The external angle is half the difference of the intercepted arcs.

  (160° -x°)/2 = 51°

  160 -102 = x = 58

Answer:

z=74

x=15

Step-by-step explanation:

74+8x-14=180

step 1 combine like terms

60+8x=180

step 2 subtract each side by 60

8x=120

step 3 divide each side by 8

x=15

Answer:

z=74

x=15

Step-by-step explanation:

z=74 because vertical angles are the same

you have to add the z and 8x-14 and set it equal to 180 because the angles at supplementary

Answer:

(25 x 3) - 14 = 61!

Step-by-step explanation:

Answer:

x=−5/2 y+ 3/2

Step-by-step explanation:

Let's solve for x.

2x+5y=3

Step 1: Add -5y to both sides.

2x+5y+−5y=3+−5y

2x=−5y+3

Step 2: Divide both sides by 2.

2x/2

=

−5y+3

2x=

−5y+ 3/2

Answer:

x=−5/2 y+ 3/2

Answer:

The answer is 8(a³ - 8b⁶)

Step-by-step explanation:

You have take out the common terms :

8a³ - 64b⁶

= 8(a³ - 8b⁶)

P.S.

a and b cannot be factorized because they are different terms.

Area of the composite figure

=Area of trapezoid + Area of semicircle

[tex] = \frac{1}{2} (15 + 11) \times 4 +\frac{1}{2} \times 3.14\times 2^2 \\ \\ = 26 \times 2+6.28 \\ \\ = 52+6.28=58.28 \: {in}^{2} [/tex]

Step-by-step explanation:

11.

tan 30 = perpendicular / base = x/ 7

1/√3 = x/7

X= 7/√3

2.

cos 30 = 7/y

√3/2 = 7/y

y = 7×2/ √3

y= 14/√3
