Answer: 3.4

Step-by-step explanation: 6-2 is 4 and 7-4=3 therefore it’s 3.4

The solution is 3.4

The value of the equation 4.2 less than 7.6 is 3.4

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is expressed as

A = 4.2 less than 7.6

Substituting the values in the equation , we get

A = 7.6 - 4.2   be equation (1)

On simplifying the equation , we get

The value of A = 7.6 - 4.2

The value of A = 3.4

Therefore , the value of A is 3.4

Hence , The value of the equation 4.2 less than 7.6 is 3.4

Answer:

32 quarters and 3 dimes

Step-by-step explanation:

you could do 4 x 8 to get to the 8 dollars so 4 x 8 = 32 so that would be 32 quarters now you got 30 cents left that will be the dimes so 3 dimes

Answer:

m < 32

Step-by-step explanation:

m/8 < 4

m < 32

Answer:

m<32

Step-by-step explanation:

multiply both sides of the inequality by 8

[tex]8 \times \frac{m}{8} < 8 \times 4[/tex]

then, reduce the numbers with the GCF= 8

[tex]m < 8 \times 4[/tex]

Answer:

4.0 meters, ∠C = 39°, ∠A = 51°

Step-by-step explanation:

Firstly, our diagram shows us that the given triangle is actually a right triangle. So we can use the Pythagorean Theorem to solve for the height of the chain:

[tex]a^{2} +b^{2} =c^{2}[/tex]

[tex](3.3)^{2} +b^{2} =(5.2)^{2}[/tex]

[tex]b^{2} =(5.2)^{2}-(3.3)^{2}[/tex]

[tex]b =\sqrt{(5.2)^{2}-(3.3)^{2}}[/tex]

[tex]b=4.0187...[/tex]

[tex]b=4.0 m[/tex]

Now, we can use the Law of Cosines to figure out one of the acute angles:

[tex]c^{2} =a^{2} +b^{2} -2ab(cos(C))[/tex]

[tex](3.3)^{2} =(4.0)^{2} +(5.2)^{2} -2(4.0)(5.2)(cos(C))[/tex]

[tex]cos(C)=\frac{(3.3)^{2}-(4.0)^{2} -(5.2)^{2}}{-2(4.0)(5.2)}[/tex]

[tex]C=cos^{-1}( \frac{(3.3)^{2}-(4.0)^{2} -(5.2)^{2}}{-2(4.0)(5.2)})[/tex]

[tex]C=39.3915...[/tex]

∠C = 39°

And since we know that all angles in a triangle add up to 180°:

∠A + ∠B + ∠C = 180

∠A + 90 + 39 = 180

∠A = 180 - 90 - 39

∠A = 51°

Answer:

Yes, they just flipped the second one around.

Step-by-step explanation:

Step-by-step explanation:

(2x-5) = 3(4+x/2) then solve for x.

2x-5 = 12 + (3/2)x

2x-(3/2)x = 17

x/2 = 17

x=34

Checking the left side, (2x-5) = 2(34) - 5 = 63.

Checking the right side, 3(4+(34/2)) = 3(4+17) = 3(21) = 63.

Answer:

Its 68

Step-by-step explanation:

Sum of all the angles is 180

63+49+w = 180

112+w=180

w=180-112

w=68

Answer:

10 - 104

11 - 25

12 - 64

13 - 109

14 - 33

15 - 90

Step-by-step explanation:

For the first 3 triangles u must add the two angles and minus it from 180

Q number 13 do the same thing then minus the number u got by 180

Q number 14 .... 66 - 180 = 33

Q number 15 it is a right angle so it is 90
