Step-by-step explanation:
Question 1:
In the expression 4y - 6x² + 5 + 9x, there are
4 terms. (4y/6x²/5/9x) A term consists of a coefficient and a variable, or otherwise a constant term like 5.
Question 2:
4(6x - 5) - 7x
= (24x - 20) - 7x
= 17x - 20.
Therefore the correct answers are
the 1st and 2nd options.
Question 3:
3x - 8y + 11x - 4 + 5y
= (3x + 11x) + (5y - 8y) - 4
= 14x - 3y - 4.
The 4th option is correct.
Question 1
There are 4 terms.
They are 4y, 6x^2, 5, and 9x.
Terms are separated by operation signs (+, -, ×, ÷).
Even if a constant is multiplied by a variable, if there isn't a multiplication sign, it's one single term.
Question 2
Use the distributive property. Multiply the term outside the variable by the terms inside.
4×6x = 24x
4×(-5)=-20 (there's a negative sign incase you don't see it)
24x-20-7x
Since 24x and 7x are like terms, you can subtract them.
24x-7x=17x
17x-20
You can see the first and second choices are correct.
Question 3
Combine the like terms.
The like terms are
3x and 11x
-8y and 5y
-4
Add them all.
3x+11x=14x
-8y+5y=-3y
-4
So the expression simplified is...
14x-3y-4
It's the third choice.

15 men can dig a trench og 90m in 3 hours. how long will it take 16 men to dig a trench of 48m long?
Answers
Answer:
1.5 hours
Step-by-step explanation:
Answer:
1.5 hours
Step-by-step explanation:
15 men can dig a trench 90 feet deep in 3 hours. So, first, we have to divide 90 by 3 to find the depth that 15 men can dig in 1 hour.
90/3 = 30
Next, we need to divide 30 by 15 to find how deep 1 man can dig in 1 hour.
30/15=2.
Now, since there are 16 men in this second project, we need to multiply 16 by 2 to find how much 16 men can dig in 1 hour.
16x2 = 32.
Finally, we have to add 16 to get 48.
Since we added the depth for 1 hour plus the depth for half an hour to get the total depth, we can say that 16 men can dig 48m in 1.5 hours.

Step-by-step explanation:
Total number of adults in the survey = 150
Number of women = 80
Number of men = 150 - 80

Ratio of men : women = 70 : 80
= 70 /80

I need help 6x-2y=10 x-2y=-5 solve by elimination
Answers
[tex] \begin{cases} 6x - 2y = 10 \\ x - 2y = - 5 \end{cases}[/tex]
Solve the system of equations by eliminating either x-term or y-term. We will eliminate the y-term as it is faster to solve the equation.To eliminate the y-term, we have to multiply the negative in either the first or second equation so we can get rid of the y-term. I will multiply negative in the second equation.
[tex] \begin{cases} 6x - 2y = 10 \\ - x + 2y = 5 \end{cases}[/tex]
There as we can get rid of the y-term by adding both equations.
[tex](6x - x) + ( - 2y + 2y) = 10 + 5 \\ 5x + 0 = 15 \\ 5x = 15 \\ x = \frac{15}{5} \longrightarrow \frac{ \cancel{15}}{ \cancel{5}} = \frac{3}{1} \\ x = 3[/tex]
Hence, the value of x is 3. But we are not finished yet because we need to find the value of y as well. Therefore, we substitute the value of x in any given equations. I will substitute the value of x in the second equation.
[tex]x - 2y = - 5 \\ 3 - 2y = - 5 \\ 3 + 5 = 2y \\ 8 = 2y \\ \frac{8}{2} = y \\ y = \frac{8}{2} \longrightarrow \frac{ \cancel{8}}{ \cancel{2}} = \frac{4}{1} \\ y = 4[/tex]
Hence, the value of y is 4. Therefore, we can say that when x = 3, y = 4.
Answer Check by substituting both x and y values in both equations.First Equation
[tex]6x - 2y = 10 \\ 6(3) - 2(4) = 10 \\ 18 - 8 = 10 \\ 10 = 10 \longrightarrow \sf{true} \: \green{ \checkmark}[/tex]
Second Equation
[tex]x - 2y = - 5 \\ 3 - 2(4) = - 5 \\ 3 - 8 = - 5 \\ - 5 = - 5 \longrightarrow \sf{true} \: \green{ \checkmark}[/tex]
Hence, both equations are true for x = 3 and y = 4. Therefore, the solution is (3,4)
Answer[tex] \begin{cases} x = 3 \\ y = 4 \end{cases} \\ \sf \underline{Coordinate \: \: Form} \\ (3,4)[/tex]
