Answer:
it's 3. how could u not know that 0.4 x 3 = 1.2 duh
The value of the expression is 3.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
1.2 ÷ 0.4
= 1.2 / 0.4
The decimal point gets canceled.
= 12/4
= 3
Thus,
The value of the expression is 3.

Solve for x by writing the equation in exponential form.
log7(2x + 17) = 2
Given :-
log 7( 2x +17) = 2 .To Find :-
The value of x .Solution :-
Given logarithmic equation is ,
[tex]\longrightarrow log_7(2x +17) = 2 [/tex]
As we know that ,
[tex]\longrightarrow log_a b = c [/tex]
can be rewritten as ,
[tex]\longrightarrow a^c = b [/tex]
So , that
[tex]\longrightarrow 7^2 = 2x + 17 [/tex]
Simplify ,
[tex]\longrightarrow 49 = 2x + 17 [/tex]
Subtract 17 from both sides ,
[tex]\longrightarrow 2x = 32 [/tex]
Divide both sides by 2 ,
[tex]\longrightarrow x = 16 [/tex]
Hence the required answer is 16 .

Three integers sum to 57. The second integer is twice the first integer. The third integer is seven less than five times the first integer. What are the three integers?
Answer:
a=8
b=16
c=33
Step-by-step explanation:
Let's call the integers a, b, and c. (a is the first, b is the second, and c is the third.)
a+b+c=57
Write the second two sentences as equations.
b=2a
c=5a-7
Plug in these values of b and c to the original equation.
a+(2a)+(5a-7)=57
Solve for a:
a+2a+5a-7=57
8a-7=57
8a=64
a=8
Now, plug in your solution for a into the equations for b and c to solve for them.
b=2a=2(8)=16
c=5a-7=5(8)-7=40-7=33
You can add up your answers for a, b, and c to make sure you're correct.
a+b+c=8+16+33=57
I hope this helped!

90 degree angle is divided into two sides
Answers:
3x + 40 =64
4x - 6 =26
Step-by-step explanation:
So we are dealing with 2 complementary angles with both add up to 90 degrees. We can write an equation that shows this:
(3x+40) + (4x-6) = 90
Combine like terms
7x + 34 =90
Isolate x
7x = 56
x = 8
Now that we found x, all we have to do is substitute it in the equations:
3x + 40 = ?
3(8) +40 = ?
24+40 = ?
64 = ?
4x - 6 = ?
4(8) - 6 = ?
32 - 6 = ?
26 = ?
Answer:
3x+40= 66
4x-6= 26
Step-by-step explanation:
3x+40+4x-6=90˚ (because the square on the angle represents a 90˚)
Add 4x and 3x
Which is 7x
40 minus 6 is 34
The equation now looks like this:
7x+34=90˚
Subtract 34 on both sides:
7x=56
Divide 7 on both sides:
x=8
For 3x+40
Substitute x with 8
the equation now looks like this:
24+40 Which is 66
For 4x-6
4 times 8 is 32
32 minus 6 which is 26
Hope this helps!

Answer:
3/4= 0.75
Step-by-step explanation:
4 can be divided into 3 parts but it will be lower than 1.
think of it this way, there are 4 groups and you have to divide 3 things equally into the 4 groups.
because you can't do a whole number, it will be a decimal.

Four less than the product of a number and 8 is twice the sum of the number and 10 what is the number
Answer:
x=4
Step-by-step explanation:
Four less than the product of a number and 8:
8x−4
is twice the sum of the number and 10, so
8x−4=2(x+10)
Simplify.
8x−4=2x+20
Add 4 to both sides, which is
8x=2x+24
Subtract 2x from both sides:
6x=24
Divide 6 from both sides to isolate the x
x=4
-how I got 20
8x-4=2(x+10) x=8 so 8+10=18 18+2=20

Which angle is adjacent to <1?
Please help asap! really important!!
Answer:
4th graph
6th graph
3rd graph
Step-by-step explanation:
Linear = y = x + 3
it is 4th graph
when you substitute x = 0 y is 3
and when y = 0 x is -3
Quadratic = y = 3x^2
It is 6th graph
for both positive and negative values of x, y is rapidly increasing
Exponential = y = 3^x
it is 3rd graph
for x = 0 y value is 1 because 3^0 = 1
for positive values of x, y is exponentially rising
for negative values of x it is nearly almost touches zero
WILL MARK BRAINLIEST <3 Each of the letters in the word "HANDIWORK" are on separate cards face down on the table. If you pick a card at random, what is the probability that the letter on it will fall between "F" and "Q" in the alphabet?
5/9
3/9
1/2
7/9
The probability that the letter on it will fall between "F" and "Q" in the alphabet is 5/9. Option A is correct.
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome/Total outcome
Given the word "HANDIWORK", the total letters in the word are 9 letters.Total outcome = 9 lettersFor the number of events, we will have to find the letters between F and Q in the "HANDIWORK". The letters are n(E) = {H, N, I, O, K}Hence n(E) = 5Pr(the letter on it will fall between "F" and "Q" in the alphabet) = 5/9
Hence the probability that the letter on it will fall between "F" and "Q" in the alphabet is 5/9
