You can use system of linear equations to find the solution.
The cost to customer to buy 5 tulips and 6 roses will be $17.75
Cost of buying 5 tulips and 6 roses.
By given data, we have:
7 tulip + 9 roses costs $25.90
or
And
4 tulips + 8 roses costs $19.8
or
Thus, we have two equations.
From equation first, we have:
Substituting this value in second equation, we get:
Thus, we have:
Thus, the price of a tulip = x = $1.45
and the price of a rose = y = $1.75
Now, calculating price of 5 tulips and 6 roses:
Thus, the cost to a customer who buys 5 tulips and 6 roses would be $17.75

It will cost a customer $17.75 to buy 5 tulips and 6 roses.
Step-by-step explanation:
Let,
Cost of one tulip = x
Cost of one rose = y
According to given statement;
7x+9y=25.90 Eqn 1
4x+8y=19.80 Eqn 2
Multiplying Eqn 1 by 4
Multiplying Eqn 2 by 7
Subtracting Eqn 3 from Eqn 4
Dividing both sides by 20
Putting y=1.75 in Eqn 1
Dividing both sides by 7
Cost of 5 tulips and 6 roses = 5x+6y = 5(1.45)+6(1.75) = 7.25+10.50 = $17.75
It will cost a customer $17.75 to buy 5 tulips and 6 roses.

If all plants had the same kind of roots, it would impact their ability to access nutrients, water, and support, leading to ecological imbalances and reduced biodiversity.
Plants possess various types of roots suited to their specific habitats and requirements. These roots serve essential functions such as anchoring the plant, absorbing water and minerals from the soil, and storing energy. If all plants had identical roots, several significant issues would arise.
1. Nutrient Competition: Different plants thrive in different soil conditions. Some have shallow roots to capture nutrients from the topsoil, while others develop deep taproots to access nutrients in deeper layers. If all plants had the same type of roots, they would compete intensely for the same resources, resulting in imbalanced nutrient depletion and decreased soil fertility.
2. Water Scarcity: Plants adapted to different environments have unique root structures that help them survive varying water availability. With uniform root systems, some plants might struggle to obtain sufficient water in arid regions, while others might face waterlogging in wet areas, ultimately affecting their growth and survival.
3. Ecosystem Disruption: Biodiversity relies on the diversity of plant species, each contributing to the stability of an ecosystem. Uniform root systems would lead to a reduction in plant diversity, impacting the overall ecosystem. Animals, insects, and microorganisms that depend on specific plants for food and habitat would also suffer, triggering a ripple effect throughout the food chain.
4. Soil Erosion: Plants with diverse root structures help prevent soil erosion by binding the soil together. If all plants had the same roots, soil erosion could increase, negatively impacting soil health, water quality, and the stability of landscapes.
5. Adaptation and Evolution: Variation in root systems has evolved over time to help plants adapt to their environments. A single type of root would hinder plants' ability to survive changes in climate, soil conditions, and other ecological factors.
In conclusion, the diversity of root systems among plants is essential for maintaining healthy ecosystems, preventing resource competition, and ensuring the long-term survival of various plant species.

Answer:
all of the plant would die out
Step-by-step explanation:
so you know how a cactus has very long roots so that it can reach the water in the desert. And a dandelion has short roots because it rains often in its habitat. so if all plants had the dandelion's roots, the cactus would die because it needs longer roots then the dandelion does.
The answer is D.
Take a look at the x-axis and the y-axis. In the x-axis, we see "time," and in the y-axis, we see "distance from Lisa's house." Since Lisa is returning home, the distance should be shorter (negative), and D. is the one the most "negative" (I would say) in the graph. Plus, it's the latest in time. Since she left home from a trip and returned, D. would be logically correct to say that she's closer to home.
B) 2.4 miles
C) 4.2 miles
D) 12 miles
