4 × (8 + 5) + 9
Parentheses first
4 × (13) + 9
Then multiply
52 +9
Then add
61
Answer:
Step-by-step explanation:
One of the easier approaches to graphing a linear equation such as this one is to solve it for y, which gives us both the slope of the line and the y-intercept.
x-3y=-6 → -3y = -x - 6, or 3y = x + 6.
Dividing both sides by 3, we get y = (1/3)x + 2.
So the slope of this line is 1/3 and the y-intercept is 2.
Plot a dot at (0, 2). This is the y-intercept. Now move your pencil point from that dot 3 spaces to the right and then 1 space up. Draw a line thru these two dots. End.
Alternatively, you could use the intercept method. We have already found that the y-intercept is (0, 2). To find the x-intercept, let y = 0. Then x = -6, and the x-intercept is (-6, 0).
Plot both (0, 2) and (-6, 0) and draw a line thru these points. Same graph.
Answer:
Each knight will 4.8 hrs spend on guard in one day
Step-by-step explanation:
A castle has to be guarded 24 hours a day 5 knights are ordered to split each day's guard duty equally
Each knights has to guard equally l.e for equal time .
That means 24 hours time has to be equally divided among the 5 knights
= 24 / 5 = 4.8
Each knight will spend on guard in one day = 4.8 hrs
Answer:
99
Step-by-step explanation:
That quadrilateral equals to 360. So i had to add the numbers which equal 261. Then i did 360-261=99.
A and b can do a piece of work in 12 days. If a alone have to finish the job among b and c so
A and b=12
A (24 days alone without b)
So if b and c 15 days and c 20 days. If a have to do all I would add 24 and 15 and 20 which would be 59 days
