2 answers:

5 0

1/2 (t+8) = 3/4t
1/2t + (1/2) * 8 = 3/4t
1/2t + 4 = 3/4t
1/2t - 3/4t = -4
2/4t - 3/4t = -4
-1/4t = -4
t = (-4) / (-1/4)
t = (-4) * (-4)
t = 16

Without actually carrying out the steps of multiplication, determine whether the product of 15.1 and 0.9 will be larger or small

yan [13]

Answer: Smaller

Step-by-step explanation: The product of 15.1 and 0.9 will be smaller than 15.1. This is because 0.9 is smaller than 1 and since 15.1 * 1 is 15.1, we know that anything smaller than 1 will result in the product of it and 15.1 being smaller.

Would appreciate brainly <3

Jay estimates that a basketball weights about .5 pounds. Shawna estimates that a basketball weights about.05. Whose estimate is

Natasha_Volkova [10]

Answer:

Jay's estimate is closer to the actual weight of the basketball

Step-by-step explanation:

The standard weight of an NBA basketball is 1.4 pounds.

Judging the accuracy of Jay's and Shawna's answer based on their percentage error when compared with the standard, we have that Jay's answer has a lower error as shown below

Error = (Standard value - Estimated value)/ Standard Value ×100

Error in Jays answer = $\frac{1.4 - 0.5}{1.4}$ × 100 = 64.28 %

Error in Shawna's answer = $\frac{1.4 - 0.05}{1.4}$ × 100 = 96.42%

From this, It is obvious that Jay's answer has a lower percentage error when compared to the actual value.

-4x + 11y = 15 x=2y Solve for y and x

Stolb23 [73]

Answer:

to find Y

-4x + 11y = 15

x - 2y = 0

equal= -3x + 9y= 15

since x=2y

-3(2y) + 9y = 15

-6y + 9y =15

3y = 15

y = 15/ 3

y = 5

to find x

using x=2y

since

y=5

,therefore

x= 2(5)

x= 10
