2. 7x = 5 + 5x solve

Mathematics
1 answer:
Tresset [83]3 years ago
4 0

Answer:

x = 2\frac{1}{2} or \frac{5}{2}

Step-by-step explanation:

Subtract 5x from both sides. This leaves us with 2x = 5. Now divide both sides by 2 to isolate x. If you want an improper fraction you can stop at x = \frac{5}{2}. If you want a mixed number you will have x = 2\frac{1}{2}.

Hope this helped! Please give Brainliest.

What is the answer cos75 degrees=10/x
vova2212 [387]
To find the answer we simply work out the equation.
cos (75) = 10/x

cos (75) * x = 10. Here, I simply multiplied both sides by x to move x to the left hand side of the equation.

x = 10 / cos (75) Here, I divided cos (75) on both sides to move cos (75) to the right hand side of the equation.

The cosine of 75 is 0.92175127, so, 10 / 0.92175127 = 10.8489137

Find the tenth term of the
REY [17]

Answer:

\frac{1}{128}

Step-by-step explanation:

The n th term of a geometric sequence is

a_{n} = a (r)^{n-1}

where a is the first term and r the common ratio, hence

a_{10} = 4 × (\frac{1}{2}) ^{9} = 4 × \frac{1}{512} = \frac{1}{128}

Square pyramid is made up of a base with a side length of 10 inches and faces that are triangles with a height of 12 inches what
Nataly [62]

The surface area of the square pyramid is 360 in²

Explanation:

Given that the side length is 10 inches.

The height of the pyramid is 12 inches.

We need to determine the surface area of the pyramid.

The surface area of the pyramid is given by

SA=s^2+2sl

Where s is the side length and l is the slant height.

The slant height can be determined using the formula,

l=\sqrt{h^2+b^2}

where h = 12 and b=\frac{s}{2} =5

Substituting these values in the formula, we get,

l=\sqrt{12^2+5^2}

 =\sqrt{144+25}

l=\sqrt{169}

l=13

Thus, the slant height is l=13

Now, we shall find the surface area of the pyramid.

Substituting l=13 and s=10 in the formula SA=s^2+2sl, we get,

SA=10^2+2(10)(13)

     =100+260

SA=360 \ in^2

Thus, the surface area of the square pyramid is 360 in²
