Answer: 7 and 41/65 units
Working
The area of a triangle is found by using the formula;
A=1/2bh where A is area, b is base and h the height
substituting for given values;
12 2/5=1/2*3 1/4*h
Rewriting the values as improper fractions;
62/5=1/2*13/4*h
62/5=13/8h
h=62/5 *8/13
h=496/65
h= 7 41/65 units

Answer:

3x-2y=2

Step-by-step explanation:

The equation of line having slope (3)/(2) and passing through (-4,-7).

The\ equation\ of\ line\ is\ given\ by\ y=mx+c\ where\ m\ is\ the\ slope\ of\ line.\n\nHere\ m=(3)/(2)\n\nEquation\ y=(3)/(2)x+c\n\nLine\ passes\ through\ (-4,-7),\ it\ will\ satisfy\ the\ equation\ of\ line.\n\n-7=(3)/(2)* (-4)+c\n\n-7=-6+c\n\nc=-7+6\n\nc=-1\n\ny=(3)/(2)x-1\n\n2y=3x-2\n\n3x-2y=2

A total of 562 tickets were sold for the school play. They were either adult tickets or students tickets. There were 62 more student tickets sold than adult tick. how many adult tickets were sold ?

Answers

answer: there were 250 adult tickets sold.

explanation: write an equation for this problem.

x + (x + 62) = 562
keep in mind that x is the number of adult tickets, and (x + 62) is the number of student tickets.

now solve.

x + (x + 62) = 562.
2x + 62 = 562
2x = 562
x = 250

1. 12 = x + 3
2. b+0.6= -1
3. a+(-4)= -13
4. x+27= -12
5. a+(-1.2)= -5.5

Answers

1. 12=x+3    12-3=9  now try 9+3 that is 12 so x=9
2. b+0.6=-1   -1-0.6=-1.6   -1.6+0.6=-1  b=-1.6
3. a=-9
4. x=-39 I believe
5. a=-4.3
1. x = 9
2. b = -1.6
3. a= -9
4. x = -39
5. a = -4.3

Pls help will mark as brainliest

Answers

Answer:

4

Step-by-step explanation:

In the equation y=mx+b

b is the the value of y in the y-intercept

so change 2x+3y=12 into y=mx+b (Subtract 2x from both sides)

so 3y+2x-2x=12-2x

so 3y=-2x+12 (divide by 3)

y=-2/3x+4 so

(0,4) or
