Answer:

The answer is 4

Step-by-step explanation:

The area for triangle is A=1/2bh, so

A=1/2bh

7=1/2X3.5h

You would multiply 1/2 and 3.5 together and get 1.75. Then you would divide 7 by 1.75 to get the height, which is 4

Jim's speedboat can travel 24 miles upstream against a 4 mph current. In the same amount of time it travels 26 miles
8_murik_8 [283]

Answer:

speed of the boat = 100 mph

Step-by-step explanation:

Let x = speed of the boat

upstream speed = x - 4

downstream speed = x + 4

time = 24/(x - 4) = 26/(x + 4)

Cross multiply:

24(x + 4) = 26(x - 4)

24x + 96 = 26x - 104

104 + 96 = 26x - 24x

200 = 2x

x = 100 mph

Here is your answer

B. (12,30)

REASON:

Given,

y= 2x+6 .......(i)

3x-y= 6 .......(ii)

Putting the value of y from eq.i in eq.ii we get

3x-(2x+6)=6

3x-2x-6=6

=6+6

x=12

Putting x=12 in eq.i we get

y= 2x+6

y= 2×12+6

y= 24+6

y= 30

So,

\bold{x=12 and y= 30}

Hence answer is (12,30) in which x=12 and y=30
