Answer:

92

Step-by-step explanation:

Let the number be x.

As per the question,

3/4x - 18 = 1/2x + 5

(4)3/4x - (4)18 = (4)1/2x + (4)5

3x - 72 = 2x + 20

x = 92

The number is 92.

Answer:

  • solved below.

Explanation:

  • \sf \frac{3}{4} x-18 = \frac{1}{2} x +5

collect variables:

  • \sf \frac{3}{4} x - \frac{1}{2} x = + \ 5 + 18

simplify:

  • \sf \frac{1}{4} x = 23

final answer:

Help me solve this questions with steps please
Flauer [41]

Answer:

B

Step-by-step explanation:

Since the triangle is right use the tangent ratio to find x

tan22° = \frac{opposite}{adjacent} = \frac{203}{x}

Multiply both sides by x

x × tan22° = 203 ( divide both sides by tan22° )

x = \frac{203}{tan22} ≈ 502.5 m → B

in mrs. wallace class's science class, 1/2 of the students are boys. Of the boys , 1/8 are left- handed. what fraction of the st
o-na [289]

Answer:

1/16 of the class are left handed boys but we do not know the amount of left handed girls so we cannot be sure.

Step-by-step explanation:

1/2 * 1/8 = 1/16

there is still no way to be sure of how many girls are left handed so you should probably make a note by the problem so the mistake on the test will be realized

To increase an amount by 3%, what <br> single multiplier would you use?
Yuki888 [10]
The right multiplier is 1.03. Because x*1.03=x*(1+.03)=x+.03x
And .03x is exactly  3% of x.

Anthony grew 64 plants with 32 seed packets.How many seed packets does Anthony need to have a total of 90 plants in his backyard
adelina 88 [10]
Let the total seed packets needed Anthony to have 90 plants be x.

then,
64:32 :: 90:x
2:1 :: 90:x
90 = 2x
x = 45 seed packets.

________________________

64 plants = 32 seed packets.
1 plant = \frac{32}{64} = \frac{1}{2} seed packets.

90 plants = \frac{1}{2} \times 90 = 45 seed packets.

Anthony need 45 seed packets to have 90 plants.

!! Hope It Helps !!
